Remove 0.95 factor for packet framerate

Browse source 
It could make things stutter, especially if cl_maxfps was deliberately
set to a fraction of the display refreshrate (as it'd target a few
frames less).
The 0.95 factor was supposed to ensure that we don't have more packet
frames than renderframes (or two packet frames in a row without
rendering in between), as that apparently breaks the movement prediction
code. We now ensure the same thing my not running a packet frame if no
render frame is run at the same time.
