PyRna float/bool/int slicing.
- fixed slice assignment.
- fix for slowdown where getting a slice would get the entire array and free it for every item in the array (malloc and free for arrays >32).
- fix for thick wrapped returning an array referencing the original pointer when coercing into a mathutils type failed.

TODO
- slice assignment currently only sypports lists.
- dimensions are ignored for multidimensional arrays.
