- basic groundwork for render feature visibility flags. I haven't gotten very far with it yet, but since I am taking a break I am going to commit what I have and continue it later.

Browse source 
todo:
* call a render class function in D_Main that enumerates the capabilities of the current renderer into a global variable to be accessed later
* add a debug-specific cvar to always show all actors, regardless of these filters
* put in checks in the renderer themselves that check both flagsets and reject rendering of any sprite/model that does not fit the definition's criteria
