[Bf-docboard] Freestyle documentation

[Bastien Montagne]

Hi guys,

I worked the past two days to wikify that google doc [1] into our 
official wiki manual.

Currently it is mere but a reference (with a few weak points/fuzzy areas 
still), and really needs some screen caps of the UI. I will see what I 
can do about that later point at least in the next days...

This mail is also to acknowledge and thanks every body who worked to the 
google doc, especially Bong Wee Kwong (light BWK), Tamito Kajiyama, and 
Lee Posey.

Best Regards,
Bastien
