Moved raylib webpage to docs folder

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. :)

+*
+*   raylib [shaders] example - Apply a shader to some shape or texture (adapted for HTML5 platform)
+*
+*   NOTE: This example requires raylib OpenGL 3.3 or ES2 versions for shaders support,
+*         OpenGL 1.1 does not support shaders, recompile raylib to OpenGL 3.3 version.
+*
+*   NOTE: Shaders used in this example are #version 330 (OpenGL 3.3), to test this example
+*         on OpenGL ES 2.0 platforms (Android, Raspberry Pi, HTML5), use #version 100 shaders
+*         raylib comes with shaders ready for both versions, check raylib/shaders install folder
+*
+*   This example has been created using raylib 1.3 (www.raylib.com)
+*   raylib is licensed under an unmodified zlib/libpng license (View raylib.h for details)
