Adds GL namespace. Deprecates the `ccGLFunctionName` functions. New functions are `GL::functionName`
Also, converts the class `DrawPrimitives` into a namespace
`Menu::STATE_XXX` -> `Menu::State::XXX`
Removes more Hungarian notation
Removes Configuration::Type <- I added it a few months ago, and it was not being used. It is safe to remove it
Transition::ORIENTATION_XXX -> Transition::Orientation::XXX
Image::FORMAT_XXX -> Image::Format::XXX
Image::_function() -> Image::function() // private methods should not start with '_'
DrawPrimitives::drawColor() -> DrawPrimitives::setDrawColor()
And fixes Premultiplied Alpha in PVR v3 images
And tests are updated with the new functions
