- path functions bpy.utils.script_paths(), bpy.utils_preset_paths(subdir)
- further simplified presets, use a generic draw function for preset menus and define the preset subdir and operator in the class
- bpy is now a python package, this makes it easier to add utility modules and adjust python startup which was previously using verbose Py/C api. Access should not be any slower since both C and Python modules use dictionary access.
- loop over scripts and load via python (currently F8 reload isnt working, will add back shortly)
- the C module is kept but renamed to _bpy and not meant for direct access from anything but the bpy package.
- bpy_types.py is an exception since it runs before the bpy package is initialized.
