Comment 2 for bug 1745587

I would like long naming, especialy non copper layer: they are not dedicated as User1, User2, Cmts, Dwgs. To me it looks like I can do what I want with theses 4 layers, so renaming them to:
"plastic_case_without_ribs"
"brass_insert_injection_molding"
"test_fixture_top_push_pin"
"test_fixture_bottom_test_nail"

Makes sense, as when exporting, the layer name is in the filename.
