* Change win32 client Sys_Sleep so it ONLY sleeps since before it was waking on

Browse source 
more or less any input event; fine for the server, not so much use for the
  client
* In the main loop, don't bother sleeping if it's going to be less than 10ms as
  the methods we're using to sleep at the moment aren't very precise
* Add Sys_PlatformInit for platform specific initialisation
* In win32 Sys_PlatformInit force selection of the DirectX SDL backend in order
  to get better fullscreen mouse input (in conjunction with a patched SDL DLL
