Small Fixes + Continuing Support for Changing Turn

Filled out deployment(), deployBlip(), revealPhase() and actionPhase()
in the Game class.
Action doesn't extend Monobehaviour.
Pathfinding doesn't create a large number of Debug.Logs.
Map.placeUnit() now correctly sets the unit position if placing the unit
in a deploymentArea.
