WOOHOO! The hardcoded framerate cap is gone! cl_maxfps 0 now allows an

unbounded frame rate (you can still set it to clamp your fps to, for example,
your monitor's refresh rate), and cl_maxnetfps 0 is now based on your network
rate.

The NetQuake-compatible targets now also have an unbounded framerate. This is
OK, because the built-in server uses its own tick rate.
