Add support for the Mnesys viewer, used on several french websites, including memoirevive.besancon.fr

See https://github.com/lovasoa/dezoomify/issues/361

Add support for detecting IIIF images directly from their tiles.
Notably, this makes this extension work with gallica.bnf.fr, the french national library website.

The addon's state is now clearly visible from it's icon:
- it is grey when inactive
- and blue when it is actively listening for requests to zoomable images

Bugs with the click behavior not reflecting the actual addon's state were fixed.

This extension now requires LESS permissions ! I was annoyed having to ask the permission to follow all of an user's navigation. Now, when a zoomable image is found, it is kept until you click on it. So there is no need to follow the user to know when he leaves a website.

- Fixed a bug that ocured when using the addon in two different tabs
- Add usage information to the addon's tooltip

The extension does not listen to all your network requests anymore. It starts intercepting requests only when you click it. It then shows a small notification badge when it finds an image.

Fixed a bug where the icon was not showing when navigating to a zoomable image on google arts and culture from a page without a zoomable image.
Fixed a bug where the same zoomable image was opened twice when clicking on the extension's icon.
