Implement tree object and choose from 20 random textures
Add TmxLevelLoader class which loads the level + objects dynamically from the tmx file. Also implement physics. Plus theres a registered contactListener which can be used to detect contact between bodies
Clean up
Merged branch dave into master.
Refactored ResourcesMangager, SceneManger a lot. Much better resources handling now.
Fixed some problems. Sometimes I still get an OutOfMemory error. I think we have to minimize our textures. :(
