Removed the Graphics namespace from VBO/Shader
_setArray now correctly update array

Also added indices method and pointer to struct
Wrong attributes type in Shader "compile" func
compile -> compileFromSource / compileFromFile

Shaders can now be directly compiled from source code
setColors and setTexCoords had wrong param
(Still working on VBO)

Could factorize "setArray" functions
Added sendUniform functions
Added Attrib to Shader

And moved glCreateProgram from compileFromFile to compileFromSource (as
the first call the second)
