AnnouncerManager gets Lua bindings, and now exists at ANNOUNCER.

New bindings:
ANNOUNCER:DoesAnnouncerExist(sAnnouncer) - returns a bool
ANNOUNCER:GetAnnouncerNames() - returns a table of strings
ANNOUNCER:GetCurrentAnnouncer() - returns a string
ANNOUNCER:SetCurrentAnnouncer(sAnnouncer) - sets the new announcer
