Make the bookmarklet toggle-able

[yodaluca23]

Make the bookmarklet toggle-able, this could be done using an if/else condition like this bookmarklet does that allows you to edit the text on anywebpage when you click it then it stops when you click it again:

javascript:if(document.body.contentEditable !== 'true') { document.body.contentEditable = 'true'; document.designMode='on'; void 0} else { document.body.contentEditable = 'false'; document.designMode='off'; void 0}

This would be a very useful addition!
