* Refactored ConCommandBase, ConCommand and ConVar class to make them all virtual, so it could interface with the game's implementation.
* Properly initialize members for ConCommand and ConVar instead of just calling memset.
* Fixed bug in ConVar registration function causing the virtual base table pointer to point to the ConCommand implementation instead of the ConVar implementation.
* Adapt codebase to new class to reduce rune-like code.
* Fixed several bugs where the global CClient pointer was used instead of the instance in question to issue bans and display information about a certain client in CBanSystem and Pylon.
* Upgraded CBanSystem and Pylon to use IPv6 instead (including IPv4 mapped IPv6 addresses). This breaks all existing banlist files! All bans have to be re-issued or the existing file has to be updated to use IPv4 mapped IPv6 addresses and renamed to 'banlist.json', and moved to the root of the 'platform' folder.
