Bump the shuttle ETD back to 3 minutes.

[Bologna Prime]

This has consistently been a source of disappointment and disgruntlement since I've seen it implemented, and I imagine there's a few people out there who would agree. The one minute shaved off the ETD is minimal for the purposes of making rounds end quicker, while having the effect of making anyone in a slightly sticky situation or inopportune position unable to get to the shuttle. Less people on the shuttle is generally more boring, both for the shuttle itself and the people who missed it, which is why it'd be pretty nice to see the original ETD restored.
