group chats:

- massive extinction of all remaining GC_* messages;
- color chooser completely moved to mir_app;
- color buttons' subclass function also moved to mir_app;
- all code management transferred to a bunch of virtual functions, members of CChatRoomDlg;
- numerous small fixes, like fix for a broken highlight in StdMsg
