Beta Backyard Kart 0.17.6

More oopsies abound! The update I put in last night addresses missing tire textures, but my untested changes to rims caused a few to become unstable. This update addresses that and adds a few new things

• Seats
  • Updated seat names no longer refer to engine size, but to their position
  • Added a no driver seat for the Offset position
  • Added a dummy for the offset position

• Tires
  • Adjusted all meshes in the mod
  • Adjusted some jbeams

• Wheels
  • Adjusted all of the meshes included in this mod
  • Adjusted all jbeams

• Frame
  • Added collision triangles to the standard frame
  • Added Colormaps to the standard frame and the floor.
    • This applies to the standard frame and the floor used on all configs at this time.

• Other
  • The standard frame configs have been updated with the new colormapping
