Quality of Life updates (part 2)

* Map Reveal
** If player has 5 or less castles to conquer, entire map is revealed automatically
** No more black spots: fully visible mountain borders now auto-expose their interior tiles
* If units have available movement points & path left, continue movement on end turn. - Thanks @Xitax!
* By default active units have gold boxes around them
* Bug fix: When attacking an enemy not on a castle, after winning, units would not move to attackers tile.
* Telestians voice added- much more to come in campaign mode
