Deleted all but input, image, texture and graphics code
Take out the Image and GraphicsManager classes

Add texture to quad and render an image.

Images are rendered now with texture binding struct
Changed from Vector3Df to vec3 from glm library
Add Sprite Render Structure
Add Input manager
Add sub image rendering system

Fixes all camera management and includes an sub image selection system
which now lets you render parts of a texture on the screen.
Update code to make VS compatibility

Fixes the OpenGL VS2013 solution to make it compatible with Windows OS.

Now a picture can be rendered using the position as the center of the picture rendering.
