Walk Cycle Implemented

Super basic walk cycle implemented, not commented or completed in any
way, and it just loops forever at the moment.
Movement context animations
Gleed Fixer + New Level Layers

Wrote an application that should fix the content root folder issues
automatically for the Gleed editor. So the designers dont have to much
about in XML. Also, the level now loads in 3 background layers, far, mid
and near, so we can have parralax effects, even though that's not
implemented yet.
Added more animations.

Added some more animations, and tried my best to make them look smooth,
but I'm no animator.
Also refactored a little of the animation loading code to make it a
little cleaner, and at least labeled the awful if-else block that
controls the animation state.
