All classes were reviewed apart from VisualServer for which no argument name is documented at all.
While doing this review, I found quite a few bugs that were fixed either in earlier commits or this one (mostly documentation bugs though, i.e. some arguments were listed at the wrong place).
-Visible 2D and 3D Shapes, Polygons, Tile collisions, etc.
-Visible Navmesh and Navpoly
-Visible collision contacts for 2D and 3D as a red point
-Customizable colors in project settings
A general speedup should be apparent, with even more peformance increase when compiling optimized.
WARNING: Tested and it seems to work, but if something breaks, please report.
-Fixed many bugs in stretch mode
-Fixes to camera project and unproject as consequence of the above
-added setget to script (documented in script doc)
-more fixes to collada exporter for blender
