Fixed possible location list population within the PowerUp Manager class
Tweaks to Abstract (some private classes made public), HPHeal works but
is not being drawn
PowerUpManager correctly parses duplicate locations for Spawn3f areas.
Does not interfere with program but additional debugging needed for
draw() for HPHeal powerup.
