-Created the RenderObject from the State. The RenderObject now only composes VBOs, SPOs and FBOs and automatically creates the right mappings between them.
-Removed the pre processor from the shader class, since we now only work with the gl getters to retrieve any locations (uniform, attribute, fragdata).
-The ShaderProgram controllers have the possibility to define the order of the attributes manually (so the programmer can work with conventions).

-Added SPOs to the state object

- VertexBuffer and FrameBuffer renamed to VertexBufferObject and FrameBufferObject respectively. This convention is more consistent regarding the State, which now gets a FrameBufferObject (FBO), VertexBufferObject (VBO) and ShaderProgramObject (SPO)
- Added controllers and objects to the Controller.hh and Objects.hh respectively
- Added corresponding managers

-State::enableFrameBuffer() -> State::bindFrameBuffer()
-Added State::useViewport()
-Added Viewport::use()
-Added VertexBuffer::enable() VertexBuffer::disable()
-Modified VertexBuffer::render to be inline and just call enable() draw() disable()

Validation methods have been added VertexBuffer::validate() and FrameBuffer::validate().
These are called by State::validate()

so that the overhead is taken out of the State::render() method.
Furthermore State::update now builds an attribute list ordered by the array-buffer-id in order to
avoid multiple bind calls of the same array buffer.

Added the class State to the framework in order to manage combinations of VertexBuffer, FrameBuffer and ShaderProgram.
The class automatically creates a mapping between the attributes of vertexbuffers and shaders.
Furthermore a mapping between FragDatas of shaders and rendertargets of framebuffers are created.

- Furthermore, I have added support for normalized attribute values.
