[Bf-python] Best way for add-on to download with Python

[Daniel Monteiro Basso]

Btw, I fixed my addon, you can try it in builds after the 54100 rev.
I draw a 'progress pie' in the 3D View because last time I tried it was not
possible (only with Python) to draw in the correct position in the Panel.
