GCD doesn't function in Classic

* Add cooldowns support on target buffs/debuffs

Duration and expiration times are not set on target buffs/debuffs
when using UnitAura. This change looks up the spellID in
LibClassicDurations and sets the duration and expiry using that
source.

This change enables the cooldown sweep that allows OmniCC to properly
display the countdown of time remaining on the buff/debuff.

Note that this only adds the cooldown on buff/debuffs applied
to the target by the player.

* set LibStub to silently fail if library is missing

Support for cooldown durations on Classic WoW is provided by
LibClassicDurations, which comes with the ClassicAuraDurations
addon. This change prevents IceHUD throwing an error if the
library is missing.

+v1.12.5:
+- (Classic) Disabled GCD module as the Classic client doesn't support tracking GCD.
+- (Classic) Packaged new LibDogTag-Unit to pick up Happiness tag fixes.
+
+v1.12.4:
+- Fixed spellcast failure events on the castbar not being handled properly. (thanks, Fulzamoth!)
+
+v1.12.3:
+- (Classic) Added support for RealMobHealth on the TargetHealth module when DogTags are disabled. (thanks, TwentyOneZ!)
+- (Classic) Added support for LibClassicDurations on the TargetInfo module to show (de)buff durations when the lib is installed. (thanks, Fulzamoth!)
+
+v1.12.2:
+- (Classic) Fixed error when changing profiles or disabling IceHUD
+
+v1.12.1:
+- (Classic) Fixed energy ticker resetting when spending energy.
+- (Classic) Fixed stack counters throwing errors and generally not functioning.
+- (Classic) Disabled target and target-of-target castbars. Added a note to the FAQ as to why.
+
+v1.12.0:
+- Initial WoW Classic compatibility
+
+v1.11.11:
+- Updated TOC to 8.2
+
+v1.11.10:
+- Fixed pet health/power not updating every time it was supposed to.
+
+v1.11.9:
+- Fixed player health never quite reaching full (and therefore never adhering to "full" alpha settings). It seems like a WoW client patch caused UNIT_MAXHEALTH to stop firing.
+
+v1.11.8:
+- Updated TOC to 8.1
+
+v1.11.7:
+- Fixed Warlock shard numeric formatting incorrectly in non-Destruction specs.
+- Possibly fixed reported bug with Brewmaster Monks' Stagger bars.
+- Added several spells to be tracked in the CC modules.
+
+v1.11.6:
+- Only show placeholder icon on custom bars when in configuration mode (fixes placeholder icon showing up for abilities the player hasn't enabled yet, like Survival Hunter's Bombs).
+- Fixed Custom Cooldown bars not displaying properly when both "ignore range" and "only show with target" were checked.
+
+v1.11.5:
+- Added Rogue's Between the Eyes stun to the CC stun bar list.
+- Added option (enabled by default) to hide mod during shell games.
+- Packaged new LibDogTag-Unit to fix hostile NPC class names displaying in all caps.
+
+v1.11.4:
+- Fixed cast lag indicator updating randomly mid-cast.
+
+v1.11.3:
+- Balance druids with Nature's Wrath now treat 50-100 astral power as full for alpha purposes (so the bar will fade to "out of combat" levels when resting around 50%).
+- Fixed the GCD and player castbar lag indicator to show up again.
+- Fixed a longstanding bug where the castbar lag indicator would sometimes be the size of the full bar if the mod never received the client-side "started casting" notification.
+- Improved reliability of castbar lag indicator. Blizzard doesn't offer the necessary events to display this with 100% certainty.
+- Fixed an error caused by the Runes module when toggling "Hide Blizzard Frame" off.
+
+v1.11.2:
+- Fixed Stagger bar to work in 8.0
+- Fixed DK Runes in graphical mode not always correctly showing runes on cooldown (curse ticket 238, thanks ithorazei!)
+- Renamed HarmonyPower module to Chi and moved saved settings over
+
+v1.11.1:
+- Fixed error when playing as a Monk
+- Fixed castbar sometimes showing gibberish text and sometimes disappearing when the cast wasn't complete yet
+
+v1.11.0:
+- Updated TOC for 8.0
+
+v1.10.18:
+- BfA compatibility
+- Added gap setting between upper and lower text (github pull request #1, thanks lrds!)
+- Fixed Roll the Bones coloring when gaining 5 buffs.
+
+v1.10.17:
+- Fixed Insanity display with DogTags disabled
+- Show text on Absorb and AltMana with DogTags disabled
+
+v1.10.16.1:
+- Added option to hide the raid icon for Info frames.
+- Updated TOC for 7.3
+
+v1.10.16:
+- Updated shard texture for Warlocks.
+
+v1.10.15.2:
+- Updated shard display for Destro Warlocks (ticket #234, thanks stencil!).
+
+v1.10.15.1:
+- Fixed an error in IceHUD's usage of GetLFGProposal()'s return values exposed by the 7.2.5 Chromie quests.
+
+v1.10.15:
+- Fixed error on 7.2 due to a CVar being removed.
+- Updated TOC for 7.2
+
+v1.10.14:
+- Fixed Holy Word: Serenity not being trackable in the Custom Cooldown module (ticket #232).
+- Updated Stagger bar to allow the user to set the max to 100% if desired.
+
 v1.10.13.1:
 - Fixed "0" showing up for some users after 1.10.13 by adding a "show when zero" checkbox to custom counters (disabled by default). Anyone who has used IceHUD for a very long time has automatically-converted custom counter modules that replaced the old "maelstrom", "lacerate", and "sunder" modules that used to exist, each of which exhibited the behavior after the last update.

    Type /icehud, expand Module Settings, expand whatever module you want to move (e.g. PlayerHealth, PlayerMana), and adjust the "Side" and "Offset" settings. "Side" controls whether it's on the left or the right and "Offset" controls how far from center it is.
 
 1. **Which module displays Monk Chi power?**
-   This module is called HarmonyPower. Harmony was the original name for Chi back when 5.0 was in beta, so I used Blizzard's name for it while I was developing for Cataclysm. I feel like it's too late to change now that many people are familiar with the Harmony name.
+   Prior to v1.11.2, this module was called HarmonyPower. Harmony was the original name for Chi back when 5.0 was in beta, so I used Blizzard's name for it while I was developing for Cataclysm. IceHUD v1.11.2 changed this module to be called Chi.
 
 1. **How do I add commas/periods into big numbers like health?**
    If you have DogTags enabled, you can open the Text Settings for the module in question and add SeparateDigits() around the tag you're trying to split up. To display Health/MaxHealth with commas, use: [(SeparateDigits(HP):HPColor "/" SeparateDigits(MaxHP):HPColor):Bracket]. To use periods instead of commas, use: [(SeparateDigits(HP, "."):HPColor "/" SeparateDigits(MaxHP, "."):HPColor):Bracket]. Use the /dog help menu to build your own similar tags for Mana, etc.

 1. **How do I get rid of the bars that showed up beneath the player in the 7.0 patch?**
    Blizzard added a "Personal Resource Display" feature in the 7.0 game client. You can disable it in the Game options -> Interface -> Names -> Personal Resource Display.
 
+1. **Why is there no target castbar for Classic?**
+   The Classic game client doesn't offer a reliable way to show castbars for anyone except the player. IceHUD doesn't support the type of inaccurate guessing at combat log details that would be required to get a semi-useful target castbar.
