Bump the shuttle ETD back to 3 minutes.

An idea for a compromise: in addition to being able to quicklaunch the shuttle early, heads can also delay the shuttle launch for up to one additional minute.

Also reduce the number of heads required to two because on lowpop rounds it's rare to have three heads at all, let alone all three in the cockpit and in agreement at the same time.

I do like this. There's a lot of reasons you might want to hold the shuttle back a bit on a per round basis

isn't this already a thing? when you scan a head ID on the shuttle thing theres a delay button as well isnt there. never seen it used though
