HealthBar

The game now has a healthbar for the tower and each enemy, which decreases every time the object receives a damage. 

The police has a starting health of 4 while the tower has a whopping 3000.  Each bullet from the turret decreases the police's health by 1 so, 4 bullets will kill them.  While, each hit from the police damages the tower by 0.1, I mean who brings a baton to a gun fight?
