WowAce

John Wellesz:
    - Fix WoWAce Ticket 2 (NPC returned by RawGetPlateType() for PVP players). TAPPED state detection is removed for now...
    - Disable now useless timer in packaged versions (still used for @debug tests)
    - - Remove periodic sanity check based on frame visibility as we are not hooking onShow() and onHide() anymore. - Throw an error (not fatal) when a frame which was never ADDED is REMOVED. - Added some debug in unpackaged version to diagnose a very strange and unreproducible reported issue where the removed sanity check was triggered.
