Add configurable Renderer backend

Browse source 
There are still some initialization errors to work through, such as
config not being initialized properly by the time GPU tries to utilize
it too. Also some life-time issues. But manually forcing it to use the
Null backnd successfully works and allows games to be "played"
headlessly.
