patch: http://www0.org/urt/pingfps.diff

Consider this as a demonstration of the concept and not a code showcase since
my coding skill is 'hobbyist' at best. But if you like it as it is, fine (I'd
welcome any improvements).





The main point of this is having a clear view of deviation of ping without
having to rely solely on visual indicators (lag meter) or the single number of
ping. Max spike and avg Spikes are utilized.

Standard deviation is calculated for each interval used which can be a more
down to earth approximation of deviation. Standard deviation is a trusted
statistical indication of variance of data.

Equivalent results come from cl_drawFPS but for FPS. This time there's no 'fps
lag meter' to compliment it.

2 intervals can be used for each. 

vars:
cl_drawping/fps
cl_drawping/fpsfontsize //size on screen
cl_drawping/fpsfirst/secondinterval // setting intervals in sec
cl_drawping/fpsposx/y //positioning on screen


It also has a cl_drawClock which I didn't remove for this patch (file is part
of a little fun project at
http://forums.urbanterror.net/topic/18972-optimized-engine-exe-a-build-of-ioquake3-to-run-urt-directly/)

cl_drawClock //HH:MM on top of screen
cl_drawClockshowseconds //also seconds

this now also has a snaps/second (serve->client) meter

shown here: http://i214.photobucket.com/albums/cc17/arxeio/sps-1.png

renewed patch: http://www0.org/urt/pingsnapsfps.diff

minor differences in rest (e.g. milliseconds time is already handled in cls, no
point syscalling it).
