More end of time round

[Zamujasa]

Pre-round length was expanded specifically because of the startup ads, too. I think it's long enough, gives people plenty of time to plan out any expeditions or plans for the round without being too long.

I'm all for adding half a minute to the post-round timer, though. Would be neat if there was something silly to do on Centcom (other than eat god-knows-what ice cream cones).
