(Hopefully) fix crashes in MP if r_aspectRatio = -1, fix #70

Browse source 
While I couldn't reproduce the crash, according to the bugreport it
happens if renderSystem->GetScreenWidth()/Height() returned 0 - and
that is indeed the only plausible reason I can imagine for it.

So I check for that case and handle it gracefully by defaulting to
4:3 FOV values.
