American Conquests unit fixes: Prussian Fussillier 2016-10-05

Bugs Fixed: Retimed some of the animations to fix annoying trouble with the sounds that were linked (i.e. the animation being much longer than the sound, so the sound would start to overlap-loop causing really loud clicking sounds). Made PediaIcons & Units_32 icon. Also re-exported the Attack A animation, and added gunsmoke to the attack (my first "major" cut and paste operation ).
