Cat M318

Little edit of the public Cat M318. Added more realistic decals, fixed the color, and added a new skidSteer attacher joint to connect to Eli's buckets,.. There is a problem conflicting with hard attach. Only use buckets that do not have hard attach unless you like invisible buckets. Going to try and rectify the issue.

Link to buckets: (Use delayed node when doing the configuration with the buckets, 20 tons are recommended).
