Class has been mostly copied from the Valve SourceSDK.
Modified to fit this particular engine.
Modifications include:
* More consistent naming.
* Using c++ style casts over c style casts.
* Using c++ datatypes for assigning default.
- nullptr and size_t for pointers and size types.
* Added proper pointer to g_pFileSystem_Stdio.
* Renamed existing one to g_pFullFileSystem (correct name).
* Obtain g_pFileSystem from the same constructor as g_pFileSystem_Stdio.
* Added new function 'GetAvailablePlaylists' to all VM's.
* Moved function 'GetAvailableMaps' from UI VM to all VM's.
* Improved logic behind 'GetAvailableMaps'.
* Server browser and SQVM now rely on 'MOD_GetAllInstalledMaps'. This new function populates the global vector 'g_vAllMaps' with all installed maps.
* Improved 'KeyValues' structure to use union for shared members.
Load ui_sdk.rpak after ui_mp.rpak.
Moved the loading of common_sdk.rpak to after common_sp.rpak/common_mp.rpak.
This should allow overriding existing assets.
Moved logging functions to dbg.h (tier0) and export them from the dll.
Added additional functions for checking bad pointers (debug only!).
Reduced output code size.
* Finished designer code for launcher gui.
* Basic implementation of setting flags for host launch option.
* Check in 'CHostState::LoadConfig' if -launcher is below 1.. if condition is met the cfg's will be executed from 'CHostState::LoadConfig'.
* Added 'StringIsDigit' utility.
* Mostly rebuild CServer structure.
* Partially rebuild CNetworkStringTable structure.
* Partially rebuild CNetworkStringTableContainer structure.
* Removed redundant patterns which are now covered in the data structure.
Moved server/client headers and implementations into dedicated subfolder.
Renamed Some classes to match the game binary (e.g. CBaseClient is now CClient).
Removed redundant files.
Add '-nodiscord' and '-nobakedparticles' to launch params for dedicated.
Add hook for 'MemAlloc_Internal()'.
Rename loggers to be more consistent with naming.
Revert omitting frame pointers.
