Changed the script UI registration to import rather then run each python script,

Browse Source 
this means it caches the compiled pyc files after importing fro the first time.

My times for importing 501 buttons_objects.py files were.
- running each as a script 1.9sec
- importing for the first time 1.8sec
- importing a second time (using pyc files) 0.57sec

Also added "bpy" to sys.modules so it can be imported.
