Lots of Initial Refactoring.

Tabified all files.
Renamed DebugPrintf to LOG.
Renamed DebugVerbosePrintf to VLOG.
Added documentation to Assert types.
Moved ReportLiveObjects to DirectXHelpers (though that was in last commit).
Removed Debug_Graphics.h

Built base of GraphicsSystem. Feels good.
Windows EOL on precompiled header.
Mostly finished GraphicsSystem. Integrated to driver.
Added source files for building Shaders.
Fixed bug. Now renders blank background.
Still need to fix crash bug on exit.
Fixed deallocation order.
Setup OnResize() for handling window size changes better.
On to HLSL reflection, WOO.
Moved allocations to class level. Makes the initial values more clear, and less redundant.
Setup Buffer creation functions.
