v0.9!! Get it while it's hot!

Hey everyone, back with an update! Beta Version 0.9

This includes everything that I wanted to add! I am very happy with Arena and I'm shipping this build to Steam for their initial evaluation / play.  I posted this here so that players could test things out and report back any bugs that I missed (and because I love ya'll)!

New Game Mechanics

1. New character controller: The previous character controller (in charge of player movement and rotation) felt pretty clunky to me when I returned to Arena development so I decided to write a new one. This version feels a lot smoother / faster / more natural.
2. Roll mechanic: Clicking the right mouse button while moving now causes the player to roll. Rolling is very helpful for dodging enemies! 
   
   1. Stamina: Rolling now uses stamina. Another resource to manage. 
3. Hit Force: Getting hit by enemies now causes a little bit of physical pushback. Stronger hits = bigger push. 
   1. Camera Shake: Getting hit also applies a degree of shake to the camera. Again, stronger hits = more shake. 
4. Spell Wheel: I noticed that during the more hectic levels I was having difficulty finding the spells I needed via the scroll wheel or the next spell button. Gameplay is fast! To remedy this I implemented a spell wheel (like the weapon wheel in DOOM or whatever other game you know if from). Now, holding down the F or Q button will slow down time and show you the spell wheel.  Quickly tapping F or Q will return you to the previously selected spell which is now displayed next to the current spell on the UI.
