Adds crew transfer shuttle voting and auto vote creation

Paprika the savior of lowpop.

~~This is half-assed for now and currently does not have any special text to differentiate transfer shuttles from normal emergency shuttles, that will come later (when me or someone else figures it out and ports it).~~ DONE

Currently:

- A vote is called for a transfer shuttle call 2 hours into the round and every subsequent hour
- It is affected by things like malf, blob, rev, etc because it basically just triggers ~~an emergency shuttle~~ a modified emergency shuttle call. If there are limits on the shuttle call (too early in the round, delta, red alert refueling, etc) it will not call the transfer shuttle.

Bay's alarms are included for all vote types, including custom admin votes, so enjoy that.

Admins can call votes for it, so can other people if admins enable it, but it's disallowed by default.
