- 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.

This fixes is to get everything working on the new auto load and properties system.
Also some other small fixes.

I decided to go through each function and UI section one by one, improving and overhauling things. Each function and section is going to be fully tested and not rushed out.

This is the best way to catch things, but also include the code base as much as possible.

Pose mode Improvements:

Batch processing for all mesh operations
Numpy-powered vertex array handling
Optimized modifier stack management
Smart shape key processing
Enhanced progress tracking

The armature validation system improvements:

Essential bones (hips, spine, chest, neck, head)
Proper bone hierarchy validation
Symmetry pair verification (e.g., arm.l/arm.r)

Added the Armature Validation modes now, we have Stritct, Basic and None, it will give a warning to the user in the panel if there have it set to basic or none.
Settings panel added, langauge change has been added back. Did some work on it to slightl improve the system.
Added dubug area, basically everything but autoload will use logging now, you be able to turn it on/off in debug settings.
Did other bits and bobs.
