* Fixes#2680: Use a shorter cable anchor model when blocked by a facade.
* Fixes#2664: Prevent anchors from creating intersection.
Replaced the simple List<ResourceLocation> for the static models with a
new container also indicating a solid part, which can be used to prevent
the creation of an intersection.
This is first update pass, which is mainly import reorganization, name
fixes, etc... Although some parts of second were done where changes
aren't important.
Errors: ~1400 -> 82.
