Separate the combat log from general chat more

[karmic frost]

GLobal chat contains XP chat, party chat, actual global chat, spell aborptions, interrupt notices, quest texts - much of this should be separated out to make it easier to follow along with what's happening. Spell interrupts and absorptions should be in the combat log, party chat should have it's own bubble, and xp should be in the party chat or combat log. It's hard to follow all the messages when so many of the elements share the same chat.

combat log goes really fast later on so it's nice that some relevant combat messages end up in the normal chat, but I think this would be fine if chats were overall more split

being able to filter any of the chat windows would be nice
