Cardboard Engine Java, pre-alpha 0.6

Pre-alpha 0.6 released! Doors are better + E1M1 wolfenstein to walk around in.

The doors now work a lot better, textures have also been added. A lot of performance bugs have been fixed in this version. The floor and ceiling have also been visually improved. Unfortunately this is not yet visible in this version.

The original map of E01L01 from Wolfenstein3D has also been added.
