Implemented Direct3D 11

Outlined the graphics system, got a basic device up and running. Simply clears the background color for now and every function is shelled, same as when I started Direct3D 9.0. Also had to create the d3d11.a file myself from the existing Direct3D11 using the LIB2A converter for MinGW, since the included one is several out of date, we can now include this file in the WinPatch.zip

LIB2A converter can be obtained here.

Adding missing quotes to path. This is only half of the job, makefiles still need fixed. Please merge when ready.
