It won't support GTK3 in the LXPanel. It's suggested to either
keep using the 1.4 branch or to use the systray icon once again.

After a discussion with Mattias Clasen and exploring alternative
options, we decided to switch back to GtkImageMenuItem as it works
best for what we want here.
In order for people to be able to compile without warnings, the
relevant parts have been wrapped in G_GNUC_BEGIN_IGNORE_DEPRECATIONS.

Borrowed from upstream libido, thanks to Lars Uebernickel.

This also means the power-manager's panel-plugin is now compatible with
most modern icon-themes.

That is until notifyd supports symbolic icons in its
notification bubbles.

This change was ported from libido upstream:
http://bazaar.launchpad.net/~indicator-applet-developers/ido/trunk.15.04/revision/187

Also no more deprecated warnings.

Before it was forcing the icon to a smaller size. Also switch to
notify_notification_set_image_from_pixbuf since the other method
is deprecated.

XfpmBattery was a GtkStatusIcon which has been dropped, so switch
it to a normal GtkWidget. Other minor changes to support things
removed from the Gtk toolkit.

This starts the port to GTK3. The deprecated warnings for GTK
dropping the system tray are ignored, we can deal with that in
GTK4.
