Changed Unit to GameObject, made units selectable
Forgot to include the new JS file in Battle
Changed "GameObject.GetObjType" to "GameObject.Type"
Changed the matArr variables in Map.js

They now reflect the changes made to the terms
Changed unit property names
Changed "Map.UpdateSelect" -> "Map.MoveHover"
Added logic for proper unit selection

 - Split up "Map.LightDist"; new function that clears the old lighted
   area
 - Added GameLogic module that handles selection of units, and will do
   more later
 - When a unit is selected, it properly displays the places it can move
   to; if anything other than a unit is selected, it doesn't do anything
