ABMS Roguelite: Added Fleets, User List, KIA

• The roguelite "ABMS" mode in Terran Partition now has enemy Groups, which have destroyers and battlecruisers in them; Flotillas with only battlecruisers; and Fleets with any array of units. These increase the total enemy count to 40.

• While it's currently ugly, I changed the ABMS user buttons to a list so that any number of users profiles can be accessed.

• Users that are defeated now cannot access that profile anymore as they are properly marked as KIA.

• I've temporarily removed enemies taking over player bases because it caused the player to get stuck in a constant loop of replaying the same battle when they tried to take the base back. I spent all of today trying to fix it but can't find the cause, especially since this problem doesn't happen when the player conquers an enemy base.

Next patch will space out enemies better, fix the enemy base takeover issue, and fix the menu. Final boss will come at some point after that.

I'm not sure if user ranks are working, I didn't rank up while testing at all.
