New Enemy - Roloui-Poloui

This new enemy will replace the current "spider" so that garrett can use
the spider for his "drop from the ceiling" enemy. Roloui-Poloui is a
French Rolly-Polly (or Woodlouse). He is intended to be the most basic
of enemy who basically paces back and forth.
Added Mockup of Roloui-Poloui

Further work on the new enemy, added a mockup for team approval.
