- Implemented sv_overridegetcvar: This will override the return value for GetCVar checks for certain CVars marked with the CVAR_OVERRIDEGET flag. Instead of returning their true value, they only return defaults instead.

- Implemented dummy CVar vid_renderer with a default value of 1. This allows mods not designed for the software renderer to run if sv_overridegetcvar is turned on.
