Branch: im.pidgin.pidgin

Modified files:
        pidgin/gtkroomlist.c

ChangeLog: 

Add tooltips when hovering over rooms in the roomlist so the full channel
topics can be seen more easily. It's mostly copy & paste from gtkblist.c,
so could probably be cleaned up as these tips don't need all the complexity
of the blist tips.
