[IMP] web, web_editor, *: add media image optimize dialog

* = website, website_blog

The goal is to give the user an opportunity to optimize his images before using
them.

For this we introduce a preview/configuration dialog after every image upload,
where appropriate default values are filled for the quality and resolution,
based on where the image is going to be used. Since this is not going to be
perfect all the time, we still allow the user to configure them, and we display
a preview to ease this process.

Indeed it is important for SEO and for usability in general that the images are
as light as possible in size.

Technically the original image is uploaded and saved first, and then it can be
optimized. This way the upload only happens once, and the preview can be
computed from the already saved image.
