add skeleton/martian/bugman/fishman/lizardman to character customization

I'd really like to see the various alien races have some interesting advanatages/disadvantages, like the fishpeople being able to breath in the pool, but requiring regular dips to stay moisturized.

This is a line of thought that ends up in 'is it really necessary for the foxman's tail to act as a stunbaton, thread #17' several months down the line.

this is a line of thought that perpetuates the whole furry boogeyman thing 

but i think some little differences would be interesting

like since martians seem to levitate, they wouldn't worry as much as stepping on glass or slipping as often at the cost of a lower sprint+move speed
