Proposed enhancement: button to unfold all code in PRs files tab

[ibizaman]

The following bookmarklet code can be used to automatically unfold folded code:

javascript:(function() {
    var interval = setInterval(
        function() {
            var expand = document.getElementsByClassName("diff-expander");
            if (expand.length == 0) {
                console.log('Done expanding');
                clearInterval(interval);
            } else {
                console.log('Expanding ' + expand.length);
                for (i = 0; i < expand.length; ++i) {
                    expand[i].click()
                }
            }
        }
        , 1000);
}());

What do you think about adding this featur as an action in this extension?
