Dii's Roofing

- Fixed ocean clay roof items to not be invalid.
- Fixed wooden roof sounds to actually be wood.
- Fixed underside textures of most roofs hopefully, they're still not perfect but their UVs aren't off the texture like they were before.

Shallow single pieces are now set to [ "MaterialName": "Roof_Shallow" ] so they can now connect to a full shallow roof piece (for corners etc)

They can be a little janky though so you might have to break, replace or try placing at different angles/directions to get the effect you want.
