laying foundations for new level gen...
added procedural mesh
still buggy as fuck :D
functional basis for new level mesh generator
missing collisions
needs a nice interface for modifying level behaviour (realtime via gamemanager?)
mesh uvs need correcting
maybe separate mesh creation into another class
Added collisions (changed everything to 3D physics!)
Made procedural mesh a little more 3D
removed old level assets
Merge branch 'levelgen'
