Motorcycle in Zmodeler

- There has to be a body texture named body00.png due to the way skins are handled atm. I think I should add a [skins] section into car config so that we can name the body textures explicitly.

in theory this would increase the effort required to make a skin. i think maybe a body.png for the default. and then body_skinname.png for others. or even a sub-directory for custom skins. at some point there could be quite allot of them. if/when that happens and vdrift automatically downloads a client's custom skin in a multiplayer game it would make it easy to clean up ones you don't need (without touching the .car files to make them out of sync with the data svn). mostly depends on how popular it gets.
