[Dextrose] [PATCH] Simple messages notification extension

Wed Dec 1 10:22:06 EST 2010
Extend jarabe.frame.notification with new graphical
elements in order to display message notifications.
These graphical elements were taken from Gary Martin
first mockups.
Messages notification are accessible through dbus
see http://library.gnome.org/devel/notification-spec/
or jarabe.frame.frame.add_message method.
This implementation only supports icons, summary
and markup body.
When a message is received a notification icon will
appear and remain present until the user reads its
content to delete it explicitly. The message palette
will behave as a message queue.
Icons-only notications will be accesible and will behave
as before.
