Add automatic emergency shuttle call (#12473)

* Add automatic emergency shuttle call

This adds a cvar shuttle.auto_call_time which is an integer N, that
calls the emergency shuttle automatically without intervention after N
minutes. This can be disabled by setting N to 0.

After a vote to extend, the shuttle will be called automatically every
shuttle.auto_call_extension_time minutes.

* Update Resources/Locale/en-US/round-end/round-end-system.ftl
