Stag Critter Added!

        

Added a Stag critter sprite with an 11- frame walk , a 10- frame run and a 24- frame idle animation.

The sprite itself is within 32x pixels with some of it going over by a bit vertically in a few frames. 

After looking back on the boar files, moving forward,  you'll now instead find just the spritesheet to keep things a little bit tidy :)
