Add option to use XEP-0392 for tab names/numbers in the infobar

This will autocolour the tabs based on their name (typically the
JID) if a new message or highlight occured. If it was a normal
new message, the colouring will be subtle (foreground instead of
background), otherwise (on a highlight or 1:1 message), the
colouring will affect the background and thus stand out much more.
