WoWChatColours

Added more aliases for channel editing, for example:
/wowchat edit society
Is now the same as:
/wowchat edit circle
or
/wowchat edit circles

Lots of channels now have shortened aliases as well as the originals:
Yell : y
Say : s
Advice : a
etc.

Currently WarParty + WarPartyOfficer have no additional aliases, as i cannot find information on how exactly they work.
