new player art

we could really use a new player design to match the zombies better
if a second skin was created I could make a way to choose at the start of game.
or a 3rd skin I could make a way to choose that too.
pretty much any number of skins.

Start by reviewing the existing player and zombie art, then inspect how the game begins and where player selection could fit. Clarify the desired number and style of skins before starting. Done means adding an agreed player design and, if included in scope, making the available skins selectable at game start.
