Attached is a patch that adds a new dialog box where
a regex can be put in to only raise the chat window
when a regex was hit. I generally only want my
window to pop forward if someone "pings" me.
Really, this is most important in group sessions.
It might be reasonable to divide this as such.
It would be nice to have a colorize plugin that
would match and color strings in messages based on a
list of regex. (or play sounds or ...)
