Update to character documentation + new Widowmaker skin soon (Patreon)

Hey everyone,

I have just made some small changes to improve the clarity of the character documentation. I have also added a new optimization method I just discovered (de-duplicating clothing textures), and I additionally added a section in the FAQ about how you can easily make give the skin a wetter look.

Soon, I will work on the next Widowmaker skin, which by the poll results will be Black Lily.

As always, please don't hesitate to ask me about any questions/bugs regarding the models!
