[Gimp-web] New FAQ

Heya,

I started rewriting our FAQ a while ago. Here's the very first draft:

https://gist.github.com/prokoudine/d4e44f14a363073fd737

It's missing some tips and tricks about stuff like drawing circles and
suchlike -- let me know what you think needs to go in or, if you wish,
fork the gist and add your stuff :)

Some restructuring might be in order, like adding headers such as
"General", "Nitpicking" etc. :) Again, please tell me about it or fork
the gist and link to your fork here.

P.S. The bit about GPL was copy-pasted form Blender's website. A
rewrite might be required.
