Granitie Casket alpha 3.1 update

Alpha 3.1 update

Updated audio volumes and ranges, audio shouldn't be overwhelming anymore.
Added a slight light around the player to view your immediate surroundings when in pitch black. 
Added 2 new tutorial popups in the tutorial cave, this is a better way to convey the navigation controls  think.
Added player squishiness. Now pushing yourself against a hard surface slowly shrinks your collision.  

This should make the game a little less frustrating to get to grips with and getting unstuck should be a little easier.
