revamp module init: no more atexit and "premain" init => no longer need to call any wstartup init function. winit section names now use group numbers instead of letters. delay_load -> wdll_delay_load dll_ver -> wdll_ver add aken build environment cleanup wsock.cpp, have it import its functions properly wsdl: defend against GameSetup calling SDL_Quit twice. This was SVN commit r5108.
