New Artfiles Added

Reorganized the artfiles and added a few .ai files that i've been
working on.

Snail Burp

Created an .ai file that contains the highlight moment of the snail
burping (and future complete burp animation sequence.
Also included a mockup still of the snail burp for team review. If we
like this, I can rescale this so we can use it as a placeholder for the
complete snail burp animation in zero.

Snail Eyes

Created an .ai file to be used to explore different expressions for the
snail through the use of it's eyes. Included is also a mockup of the
whincing eyes set.
