* Small changes in many files:

-  Trying to fix linking problems in OSX;
-  Making module .Get functions behave like the ones in Blender 2.25 - 2.27
   (Guignot pointed the incompatibility);
-  Included more types to Blender.Types;
-  Found by luck and corrected two bugs that were making Blender crash;
-  Added/updated some simple functions.
