Use the "appName" parameter in notifications to identify the source
rather than the id - use the latter to enable update and removal of
individual notifications as laid out in the desktop notification spec.
This is a rebase of the patch by Florian Müllner.
Changes notifications like:
XChat: Private message from: danw (GimpNet) blah...
to
danw: blah blah blah blah
(the "XChat" being unnecessary since there's already an xchat icon
there anyway.)

This adds some meaningful functionality to the notification icons in the tray
and in the notification pop-up and allows to switch to the application that
sent the notification.
We get the application from the notification context and set it on the source
for the notification.
