The Shadowling ability "Extend Shuttle" now prevents the shuttle from
being recalled.
- The announcement when the ability is successful now also informs the
crew of this inability to recall.
Additionally, attempts to recall a shuttle which cannot be recalled due
to the canRecall var will no longer be logged since they don't succeed.

- Hijacking the shuttle will make it dock to a new dock on the
syndicate outpost.
- Fixed shuttle_master not calling mobile/dockRoundstart().
- Only Traitors, Changelings, Vampires, Nuclear Operatives, and
Syndicate Deathsquads can now hijack the shuttle.
Currently, to_chat is literally just a proc that does user << message.
But it'll let us do output modification in the future, especially for
something like Goon's HTML chat.
Big thanks to PJB for his to_chat script, see
