Purity shield mount

The only mount added to the mod is the purity shield. It gives the player infinite flight and all directional movement that can be slowed down using the space key. It exists to give the player controls that bullet hell games have in order to make the bullet hell boss fights more easy. It also makes the purity shield fill fasterIt is crafted from 3 infinity crystals (apparently 1 drops every time you defeat the original spirit of purity) and the cosmic car key; a vanilla mount with similar yet inferior movement.
