initial work for collision detection
added prototypes for collision classes
rewrote voxeltreenode
updated .gitignore
continued work on the collision-engine
even more collision detection stuff
somewhat code-complete collision detection, will need a lot of testing and addition still
basic collisiondetections are working
added missing files
cleanup started
tuned collision detection
finished collisiondetection
fix windows build, reduce console output, better initial cluster positions
fix Worldtranform::matrix() again, must have been lost in merge.
collision detection doesn't work with rotated objects yet.
removed rotateXYZ/move/moveTo/rotateTo mess from voxelcluster, call transform if you want to move or rotate it
merge with origin
merge with origin
more testing possibilities, merge with master
fixed collisiontests for now
merge with master
