Accomplishments Viewer Visual updates

Accomplishments Viewer updates:

Desired changes:
Search bar (with autotocompletion if possible)
Different trophies for different levels of difficulty
Wooden cabinet http://www.jonobacon.org/2012/04/06/drawing-a-wooden-cabinet-in-a-gtk-application/ (maybe it could look like like the boxes in USC (for consistency)?) BTW, the Lightread guy (Jono Cooper) is good at HTML, CSS, he could be willing to help
Dark toolbar icons for themes with light toolbars (?)

A tiny quickly app that displays icons exactly the same way we do it in the viewer, yet is very simple so that it will be easier to try wooden theme out.
