Adds resting pose selection to dogborgs

-New verb to choose between resting/sitting/belly-up poses.
-New sprites for all the animated borgs (and maybe the rest later when they get anims and shit)
-Resting, sitting, and belly-up poses now come in all directions. (on the currently finished set)
-New placeholder sprite to prevent invisible borgs just in case.
-Rearranged the contents of the sprite file to a more consistent order.
-Ported the animated version of dark medihound, also gave it the poses.
