REQ: race hud ui

[meag]

Describe the solution you'd like
fourier:
Is is possible to make ezquake ui for race mode? i.e. button to turn on the race mode when on a server, show table with personal bests/global best races for a map, tutorial mode, personal progression graph with date/times of persobal bests for a day and number of attempts etc
I guess collecting stats should be done on a server side, but client could have a ui to present it nicely

would require ktx support
