Tabified DirectXHelpers and added more SetDebugObjectName overloads.
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.
