Minor thing: using blender's addon uninstaller doesn't remove the old pyd file

[thelabcat]

This issue is not your fault, moraell, but after much confusion myself I thought it might be helpful information.

To layman,
When installing and upgrading this addon, don't use blender's addon installer system as:

1. there are two versions of the addon in the archive, so blender wouldn't extract it correctly.
2. Blender's addon uninstaller wouldn't know to remove the old pyd (C++ module for python) file, and so if the old file was still in C:\Users\You\AppData, blender would revert to it, and compatibility issues with the new py script would arise.
