Fixes

- Fixes issue with addon registration which just randomly broke at some point
- Fixes issue where merge armatures decided to break due to me messing up with properties.
- Fixed issue where you still had to select the mesh in the 3D Scene for viseme creation even though we have a UI selector now.
