raylib webpage has been completely reorganized and moved from gh-pages
(a pain to work with) to docs folder. Useless libs have been removed,
webs have been renamed, etc.

Now it would be easier (hopefully) to update webpage. :)

Now it uses CharInfo data, this way, it's better aligned with the future
RRES file format data layout for sprite font characters.

BMFont loading has been improved to support unordered chars and extended
characters (up to 255)
