Preparing for release

* 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.
