Fixed robot drawing order and robot shadow appearance.
Replaced the tile assets.
Updated tile art.
Updating enumValueForType to account for new values (how did this not break something already?)
Added an opposite_actions map, for quick reference.
Fixed [#2] - implemented collision detection using a "previous position" stack, so that, for every collision, the robot undos its position to the top of the stack.  If it runs out of positions on the stack, it defaults to move downward.
Fixed [#11] - should check collisions for robots in play *only*
Refactored the extractRobotInformation to the LevelStage.js, since it will eventually load batteries too, so it doesn't make sense to be Robot.js specific.
[#5] Added Battery, which is now drawn.
[#5] Battery is now implemented!
Added proper costs for movement.  Game balancing is needed!
Increased battery level to 25.0
[#5] Oops - this check only applies to the player, not to all robots in play (took it out of the enclosing 'if')
Refactored code that appended to arrays to use the stack methods JS-Arrays provide.
Moving tests to their own folder.
Removing project file.
Changed the shadow sprite under the battery
Refactoring the Robot parameter list into a parameter map.
[#3] Adding functions for validating size of editor area (to be used later)
Merge branch 'master' of github.com:recardona/game-off-2013
