User Interface and AI Improvements

Fixes a bug that caused units that were force to retreat during Rifle or Artillery fire phases to have 0 strength points in close combat.

Fixed an issue where using the Hide Units toggle would cause the key to no longer cycle through units in a stack.

Better outline for colors in Tactics Cards dialog.

AI will be a bit smarter about attacking lone artillery units - it won't send multiple units after the same artillery piece any longer.

AI will do a better job when moving to engage an enemy. It should make better decisions about when to move, and when it does so, it should try to make sure it has an advantage.

During the Defensive Artillery Fire phase, artillery units will be moved to the top of the stacks automatically, and as you cycle through your artillery, you should see a highlighted border on the hex that contains the artillery.
