|  | When there is no '.load-more-text' element on the page, a JavaScript
error would be triggered from calling `addEventListener` on `undefined`.
Do a check for undefined to silence the error. | 
|  | New videos loaded on a page over AJAX will not have title tooltips.
Refresh tooltip titles when more videos are loaded.
Just use a timeout to make things simple. The tooltipiser will wait 3
seconds between requesting more videos and refreshing titles. This will
generally provide enough time to load the videos into the DOM unless the
network connection is really slow. | 
|  | Add manifest.json, add functionality in content script that copies the
YouTube video title into the title link's `title=` HTML attribute to
give us the tooltip. |
