Responsive theme switcher using SCSS (Responds to user theme pref)

I don't think it was in the requirements to make it respond to your windows\phone theme but it was a thing that I wanted to try out so I did

Also tested out making a button specifically for accessibility reasons (don't know how useful it might be for a non-sight user to have a dedicated theme switcher, but accessibility was one of the things that I wanted to learn aswell)

If there is any issues about wrapping <section> in the <a> element, I did that as a quick fix and didn't really think too much about it

I had some difficulties with the toggle button because this was my first time making one of them, was really satisfied with the final result
