Reconnect the server to the global timing.

Browse source 
Having the server in an own timing zone seems to simplify things but
introduces slight timing discrepancies. The most visible effect is that
the game runs a little bit too fast, especially in the first cl_maxfps
frames.

Therefor: Remove timeframes, they're unnecessary. Track the time since
the last (client|server) frame instead and pass it to the client and
server when it's called.
