The following updates have been contributed by Willian P. Germano:
* Implemented BPY_end_python function. * Implemented error handling. This results in rerunning a script after an error has occurred. No need to restart blender anymore. * Camera module supports dir() * variable assignment now calls the Python equivalent function - this has type checking and should be safer now. * Implemented the Lamp module. Used the Camera module as a template. * Implemented the Image module. * Added EXPP_ClampFloat and EXPP_intError functions to gen_utils.[ch] * Implemented 'constant' object.
