Maroon and Destroy objectives for Traitor and Changeling

Maroon
-Maroon objectives are a variation of assassination, where preventing the escape of the person also counts as a success.
-Aprox. 30% of assasinations will be maroonings instead
-Disincentivizes players from staying behind on the station when the shuttle leaves simply because "it's more safe"

Destroy
-Basically an assasination objective where the AI is the target
-Aprox. 2% chance to get this objective.
-Adds variety, counterplay between those who want to destroy the AI and save/restore/steal it
-It is entirely possible to get Destroy AI and Steal AI at the same time. While it would be difficult, it's still entirely possible to destroy your target and steal a different AI. The chances of getting both are very slim, however.
-Encourages restoring the AI over killing it wherever possible. Discourages AIs from cooperating with antagonists.

Wizards don't get these objectives, because they'd be too easy for them.
AIs aren't experimental, though, they work perfectly fine under normal circumstances.
