American Conquests unit fixes: 17th Century Sweedi 2016-10-05

Bugs fixed: In every single animation, there were pixels of semi-transparent colors on parts of the body where they shouldn't have been. Also, I made it so that it now is civ-color compliant (the shirt sleeves and pants change colors). In the attack animation, for some reason, in the NW, SW, NE and SE directions, the gun looks like the barel's bending around some object, or is not connected to the rest of the gun, which I proceeded to fix. I linked sounds to the Musketeer and Musketman, and created Civilopedia Icons and a Units_32 icon.
