ConVar class rebuild (#90)
* Implement CCvar class with mapped out vtable funcs * Rebuilded ConVar class + code overhaul to use new system * ConVar class is now properly mapped out for r2 (0x80 in size). * Reimplemented and exposed all frequently used ConVar class methods to the SDK. * Implement frequently used CCvar class methods. * Implement all CCVarIteratorInternal class methods. * Performed additional cleanup over the SDK to use new system instead. * ConVar class improvements + rebuilded ConCommand struct * Fix actual struct size for ConCommand
