Turns announcements into a datum based system to allow a variety of configurations.
Current configuration options include:
Admin logging
Which sound that should play when announced, if any
If the announcement should be stored as a newscast
Request console/standard announcements currently match priority announcements, but have a smaller style/footprint.
Player announcements now include the assignment and name of the person (or the id rather) who made it.
Have currently only updated the request console and all announcements which previously used captain_announce().
Affected automated announcements, such as shuttle messages, should be exactly the same as before.
Escape pods now no longer launch automatically during regular crew
transfers. However they can be set to launch during a regular crew
transfer by emagging the escape pod controller.
Also fixes emergency shuttle arrival announcement having the wrong ETD.
Moves all ferry shuttle processing into one place: the new shuttle
controller.
Also cleans up the emergency shuttle controller a bit more and fixes
multi-shuttle cooldown.
