Add file pasting

[Hattorius]

It should be possible to paste a file into the website (just like how imgur.com does). These files get handled just like any other.

Expected features

• After the website opens you should directly be able to ctrl+V a file into the page (no click required)
• These pasted files could be literal copied images (from other sources) or copied from the file explorer
• These files should be handles just like any other file

This doesn't have to be too hard. A simple implementation could be:

document.addEventListener('paste', function (event) {
    if (event.clipboardData && event.clipboardData.items) {
        for (let i = 0; i < event.clipboardData.items.length; i++) {
            let item = event.clipboardData.items[i];
            
            // Check if the item is a file
            if (item.kind === 'file') {
                // Get the file as a File object
                let file = item.getAsFile();

                // Use the File object
                if (file) {
                    handleFile(file);
                }

                // Multiple files? Try zipping them?
            }
        }
    }
});

At the end the "Multiple files? Try zipping them?" is a reference to #11
