Trial Guardians

Major boss rework

BREAKING CHANGE: FORMER "DECILIB" MOBS NOW HAVE THE NAMESPACE TRIAL_GUARDIANS. THIS BREAKS EXISTING DUNGEONS AND ANY OTHER REFERENCES TO THE OLD NAMESPACE. 

Removed DECI-Lib dependency. It was the wrong move for full boss mobs.

All Mobs no longer have on contact damage

Minotaur now has a charge attack

Minotaur's slam now shows more clearly if its radial or conical

Minotaur's frenzy is now phased, with more dynamic attacks rather than just moving forward unstoppably

Minotaur now has a Pylon mechanic, where he summons pylons around the arena.

Pylons can be charged into by the Minotaur to discharge and be destroyed, dealing damage and slowing enemies.

Pylons connect to each other with arcs of lightning. Passing through arcs of lightning gives the Minotaur's Charge ability a slowing effect on hit.

Hydra is no longer a coward, but still prefers range. He will no longer turn away from you and run.

Hydra strafes rather than kites now, sometimes leaping backwards to fire a rain of arrows.

Hydra now has a Hydra Fang mechanic, which involves flying fang projectiles that, after a while of flying, lock on a target and shoot towards them.

Phoenix no longer charges and explodes repeatedly.

Phoenix instead now actually hovers rather than being earthbound, retaining the previous charging, but from the air. 

Phoenix now properly chains its melee attacks.

Phoenix now has a Mechanical Bird mechanic, during which it releases mechanical birds which shoot flame and dive bomb. 

Phoenix's horizontal movement cause it to visually roll in the direction of the movement slightly.
