        File purpose:
                This file is the WinMain entry point. It will setup the clanCore
                win32 environment and then afterwards call the ClanApplication
                instance.

                This file also contain the win32 specific implementations
                of the CL_System class.

                The win32 versions of CL_SetupCore functions are also defined here.
