_new point class and update_
- adds a new point class
* point/ vector math (p + v = p, p - p = v, etc.)
* points can be transformed by matrices/quats
* wraps 'place vector' type vectors that have no magnitude
- wrapped toXXX() methods work correctly
* toXXX() will NOT wrap data (this is due to the fact that wrapped data cannot be converted)
* added a 'wrapped' attribute to mathutils classes to determine wether the object is accessing python or blender data
- added the ability to negate vectors/points with "-vec"
* deprecated vector.negate()
- added the ability to shorhand inverse matrices with "~mat" (tilde)
- conversion between vector/point with toXXX() methods
