QR Code generation has been implemented, the refresh button has been removed for the sake of keepign things simple and symmetrical. This will generate a QR code on the javascript side.
I have created this feature mainly for people that are trying to quickly transfer information from their computer to their phone extremely quickly, simply just type your Pad, click on the `QR Code` button and then pull your phone's camera out and get instant access, no longer typing the URL or sending the URL through some messaging app and wastring time.
Implemented a rate-limiting system, quite primitive and basic implementation on my part since it's looking at all requests not just the POST requests, this can be bad news if someone is using the service a ton and won't truly protect from floods as it's ip-based but should offer a level of security better than none.
Old version of FreePad which depended on a database for storing data, this was later dropped as it was pointless since we are only storing temporary data, so we moved to "v2"
