Fixed Magic Missile
Fixed Input
Changed enemy health bar

Ran into some problems with GUI trying to change the texture of the
player's health.
I think the problem lies in how we're calling the playerGUI script in
player script
New texture bars!!!!!

Mage has new texture bars now. I removed the GUI script for the bars
outside to another script called PlayerGUIBars to make it easier to
change.
Also I don't know howt rage Bar works so I don't know how to change it.
