Added a new AudioPlayer (Advanced) that can play and transition between tracks. An 'AudioTrack' is multi-source collection of AudioClip's that are split into intros, loops and outros. There are currently three tracks to specify, Environment, Music and Snippets.
Created a new Medusa prefab that has the model as child instead of baked into the top level.
Replaced the ProjectileShooterToon and instead created a separate model of it which can be selected from a regular
 projectile cannon.
Fixed rotation of medusas in a couple of levels
