Upgrade to Gtk+3

Apologies for one more patch bomb: This is an upgrade for matchbox-panel-2 to use modern dependencies, mostly Gtk+3. Most commits are again from Ross, I just fixed bugs and replaced some deprecated code.

This patchset is part of the quest to make Sato compatible with GTK+3. Complete WIP collection of patches can be found in jku/matchbox-wip branch at git://git.yoctoproject.org/poky-contrib
