This commit changes the way the UI is displayed. Buttons are bigger and square, with the status icon at the bottom. It makes use of CSS grids to show all buttons nicely aligned. It also makes the UI squishy, showing more columns the wider the screen (up to 5 columns).
This is a vue.js app that loads a JSON file from the server and uses that to generate a sound board. Audio files are put into audio/. It takes most of it CSS from kaamelott-soundboard.2ec0b4.fr.
