'Changelevel 'concommand works consistently and indefinitely now
Huge strip down in resource usage. Few things to be fixed still so idle mem usage is still balooned due to a temporary solution brought in place to prevent crashing when loading texture and material assets.
Stripping texture and material assets preloading from the root caused issues in 'CStudioRenderContext' and 'ModelLoader'. This needs to be addressed in the future
Exact line of the issue: Line 177 in opcodes.cpp:
"gCSourceAppSystemGroup_Create.Offset(0x384).Patch({ 0x90, 0x90, 0x90 }); // PrecacheMaterial"
Based on MrSteyk's dedicated patch.
Additional patches targets the disabling of the client.dll library and VGUI. The disabling of the client.dll library initialization caused several issues to be investigated still (currently loops fine in _Host_RunFrame()). but executing a map command currently makes it only load the mp_common VPK before getting stuck somewhere. Setting hoststate to a valid map with HS_NEW_GAME (manually) does something to the engine but does not force the server to load anything yet.
Added enums and classes from r5dev project.
