Feat: Implement Copy-to-Clipboard using `clipboard.js`

[nelsonic]

As a lazy person that wants to make as little effort as possible,
I don't want to have to hover over text and manually copy it to my clipboard
I want to click a button and have it automagically copy to clipboard
So that I can save 2 seconds of my busy day...

Todo

• Add a button next to each <pre> that allows people to easily copy their badge to clipboard using https://github.com/zenorocha/clipboard.js
