Slim wallet, reinforced

A reinforced version of a wallet. There are several different versions; all of them are reinforced and functionally the same. The only differences are the patterns on the front. The regular version is the original design, the dawnshard and shark versions are slightly modified versions, and the truthwatcher version has a completely different design. I included several of the source files, but they can be finnicky since they started with importing the STL directly into fusion. I somehow mostly fixed this at some point, so the template and truthwatcher f3d files should be easier to work with. The STL versions appear to be unaffected by the messiness.
