Better referencing

This commit makes changes to the way variables are referenced:

• Make types Copy when possible
• Make methods take `self` instead of `&self` where possible (trivially_copy_pass_by_ref)
• Remove unnecessary borrowing (needless_ref)
• Remove unnecessary cloning (clone_on_copy)
• Remove `ref` from match arms where possible (new Rust match ergonomics)
