Fix border shorthand serialization

Fix border shorthand serialization when sides are not identical. I think I managed to get the serialization to work as expected.

I added a check to ensure that the **border-width**, **border-style** and **border-color** were the same, before performing the serialization.

I'm still a Rust newbie, so if there's a more idiomatic way of doing things (or any critiques in general), please let me know!
