Disabled additional unnecessary DX code from patched dedicated server executable, this allows the dedicated server to run RPaks containing models without any material or texture data. This also allows us to fully rebuild all RPaks for dedicated while also omitting material/texture data to further reduce memory usage during the parsing thereof, and overall disk size.
This patch prevents 'fps_max' from being reset in 'CEngine::Frame' if 'sv_cheats' isn't set; this cvar is now bound to the server's tickrate in sdk code to save CPU time.
Added 2 new patches:
* Patch0: Unnecessary loop called from 'CModelLoader::UnloadModel'. This calls a 'nullsub' CMaterialGlue vtable method.
* Patch1: CClientState constructor; Removed due to high mem allocation during init (100MiB+). 'CClientState' is useless on dedicated, and all its feature are thereof disabled.
