Bookmarklet only works once per page load

This is generally annoying, but causes real problems for some services like Trello because the page very rarely fully reloads.  So, you can send one thing over to cardorizer, navigate around and then try and send another thing over, but since the page hasn't reloaded the bookmarklet doesn't work.

I fear that this will require changes to the code in the actual bookmarklet.
