Solved some buggs in time tracker where you could not restart it.
Fixed export with full path to export folder, defined in CMake.
Fixed argument possibility and added intensity stuff that makes it look ugly again.
Threading work for timer. To slow when trying one per pixel, but seems to be working when one per row. Will look into it some other time.
Merge branch 'develop' into octree
Able to render using real octree now. Made compiler more strict.
