Laser Defender (Clone)

v1.1:

Added sounds and text for power ups.

Tweaked sounds so that player death and asteroid death aren't so quiet.

Added Shield Graphic so you can tell when you have enough HP to live through a hit.

Fixed Hp not resetting correctly after death and respawn.

Fixed enemy AI so reds prefer moving to back rank correctly again.

Adjusted various other code settings to make game more ... "robust".
