Auto Shout Out Neo

- Fixed hard-coding of 'Common' for whispering when doing a 'Spell Cast Failure' notification.
- Changed IsInBG() to use UnitInBattleground("player") instead of looping/GetBattlefieldStatus(i)
- ISSUE: If in a dungeon party, and try to do a whisper to someone from another server, the whisper fails ("No player named '<Player Name>-<Server>' is currently playing."). However, it works in Battlegrounds. Waiting to hear back from Blizzard on this, but until then using 'Whisper Target' for the 'Party Configuration' to message someone that a spell cast failed won't work via whispering.

Beta build!  Please help out by reporting any bugs/problems.
