kingbri 43e91b150a CFG: Add groupchat support
Groupchats have their CFG defined a little differently. Chat and
global CFGs are publicly accessible within the window. As a compromise,
individual character CFGs can be injected as part of each character's
prompt. However, these CFG settings need to be adjusted in the character's
individual chats which will carry over to the group.

In addition, make this character logic gated under a checkbox to
always prefer chat unless explicitly specified. Negative cascading
is still open, so individual character negatives can be included
at any time.
