Kawe Mazidjatari 196db8660e Dedicated and SDK improvements
* Improve ConVar class (fixed several bugs).
* Hook CEngineAPI::ModInit() and set m_bRestrictServerCommands from there.
* Disable unused ConVar's and purge unused ConCommands in CEngineAPI::ModInit() for dedicated.
* Small relocation of malloc related signatures.
