AI Wander & Barker (#286)

* Retrofit the AI system with new IoC features.
Fixed bug with turret rotation.

* Added new AI WanderProcessor, and it works.

* RNG walking directions are a bit more random now.

* Wander now actually uses the MoverSystem to move.
Wander now talks when he reaches his destination.

* Adds a new Static Barker AI for vending machines, so that they periodically advertise their brand.

* Barker now says some generic slogans.
Misc bug cleanup.

* Removed useless UsedImplicitly attribute from AI dependencies, suppressed unused variable warnings instead.
