Test cloth mass type switching feature which allows the user to set some particles as static, kinematic, or dynamic.
Renamed SpringClothCollision to SpringClothContact for consistency.
Removed ShiftCenter test for visualizing the effects of external center of mass shifting. This probably must be moved into another folder since might scare the user.
Ordered some test entries such that experiments are the last defined. Those are not actually features of the library and probably must be removed from the testbed into a different project containing experiments.
Since I started altering the testbed for better maintainability, I prefered to drop this (tested) large change with a single commit. Some changes below:
Put some globals in their correct place,
Now Testbed uses the MVC pattern (Model-View Controller). This way it becomes better to maintain than using no pattern in my opinion.
Fixed some bugs in the debug draw interface.
Of course, updated almost all tests because of the differences.
Update script.
