add TargetCast support in Classic (#8)

Browse Source 
This change adds support for using LibCasterCasterino to get your
target's casting info to enable the TargetCast module. It's not as
clean as the newer retail native calls but works well enough for
most interrupts.

Note: because LibCasterCasterino is using combat log events to get
casting info if a spell cast starts and is immediately cancelled or
interrupted the log may not get updated and the cast bar will zombie
complete.

LibCasterCasterino can be found at:
