[Patch] Sidebar for gnome-control-center

[Denis Washington <dwashington gmx net>]

Hi gnomecc developers,

Because the current gnome-control-center's view with categories is quite
nice IMO, but the general usability is lacking a bit, I started to hack
on the app and programmed a sidebar to filter the canvas view by
category. It may be a bit hackish a partially un-gtk-like because it's
my first gtk+ code in C, but it works. A filed the patch as a bug:

Here's the obligatory screenshot:
