Demo for PRGE

This batch of builds should reflect the demo I'll have at PRGE. Changes include:

• Added a tutorial to the first level to help orient new players
• Added a way to disable aim assist (it is on a per-level basis, I plan on filing a bug report for this, but I figured it was important to make this feature at least sort-of available for QA purposes)
• Narrowed the aim assist so the player would have to aim a little more accurately to hit dinos.
• Fixed timing issues on animations (transitions were broken in a couple of places)
• Fixed an issue where the little water ripples around units would appear on a dino on the boat
