Theming system -  Safe skinning implementation

This is a safe skinning/theme system built into the boxee+ settings menu.

You can watch a demo here:

I have created a basic guide to creating and packaging a theme here.

At present you cannot replace or change any *.xml file.
When creating a theme you can only replace images contained within the original boxee theme.

This is done to ensure that the theme will be compatible with future versions of boxee+

I will work on a way to safely replace additional images added by boxee+.
