Fixed an issue where the notification sent about a gold building being automatically constructed was being sent to non-Lincoln players.

Volumne standardised.

Ranged Monitor can now upgrade into the Battleship.
Rewrote the code for the second part of the UA. It should work with more consistency now; buildings will also be constructed to completion and a notification sent about the event. Building these buildings now yields double production rate.

Added unique City List courtesy of SuperWaffle247.
Reduced healing of Melee Monitor to 5 damage per turn.
Fixed issue where players could build the Ranged Monitor when they weren't Lincoln.
