Plugin Registration Changes

- Re-wrote how the plugin registers itself.
- No longer need @register_wrapper classes get auto detected and added.
- The new Auto loader is much better then the old way, no longer need "if "bpy" not in locals():" this was an old way of doing things and wasn't really efficient.

 using auto_load.py provides several advantages:

- It automatically discovers and loads all modules in the addon.
- It handles dependencies between classes correctly through topological sorting.
- It manages registration order automatically.
- It properly handles unregistration in the correct order.

This approach is much less error prone and I not had any issues so far. However it still needs testing fully.

I have also start to re-organise files into folders as well, this is going to be needed so we don't have a long list of files as Avatar Toolkit is getting larger then i originally planned.
