-Replaced the rectangular with a more natural circular one.

-Added a new collision method "checkSenseCollision" in <Collision> to
check if the player has walked into a enemy sense area

-Added enemy tile collision
	-Player tile collision and enemy tile collision could be
	 merged into one method, but for now its two separated methods
	 that runs in <Collision> update();
	 
-Moved the "up,down,left,right" booleans and set/get methods to the
superclass <Character>, so that enemies also can use the collision
system, not just <PlayerCharacter>

-Temporary modified move() method in <EnemyCharacter> to illustrate what
could happen when a enemy detects the player by walking into the
senseArea. The senseArea also expands the longer a player is inside it,
to make the enemy more aware of the player the longer he sees him
-Changed the move() illustration  in <EnemyCharacter> becuase the random
algorithm was not correct.
Testing a ImageHandler.
- Added a setCurrentEnemies in <Collision> and implemented it in
<GameEngine>
- Added 3 more enemies in the maps for testing.
	-Also changed their temporary move speed for testing.
	-Removed the annoying println when you entered a sense area.
- Started on a idea for a ImageHandler.
