Changelog

v0.0.2

Removed unnecessary print.css, as it's possible to open the QR code image in a new tab (or locally, after having downloaded it), and print it.
Fixed the double QR codes that would pop up instead of one.
Added some more styling to buttons.
In style.css, all absolute units (px) are now converted to relative units (em & rem).
Replaced the qrcode.js with an uglified version of it (qrcode.min.js).
Added the option to add the encryption type.
Removed unnecessary font weights.
Turned autocomplete off for the input fields.
