User Interface Framework

The UserInterface framework is a wrapper around the graphics rendering engine that will abstract user interface (including visualization) from physics simulation.

It originated by the need to separate those two concepts during the migration to an Ogre rendering backend.

In short, it will completely replace current user interface concepts, boosting base interfaces and HUDs mainly (besides the graphics per-se... which will be nicer).

I should explain more... but in the meantime, see the prototype.
