Commit 9676ceec02 removed/replaced image files in mass_mailing
module but two of them were still used by website_mass_mailing.
This commits adds these two images in website_mass_mailing module and
use a more standard convention to define associated snippets and
link them in the snippet panel. Also lint JS files.
The "edit" action is on the "website.TopBar", which will create a new
instance of the "editor" (web_editor.editor) widget.
So if we want to do something when the "editing" start, we have to
either override "edit" of the TopBar, or override "start" or "init" of
the editor.

`mass_mailing.unsubscribe` depends on
1. `web.ajax`, as it uses `ajax.jsonRpc`
2. `web_editor.base`, to explicitely wait
for all dependencies to be loaded,
so the DOM can contain `o_unsubscribe_form`

Each module can return a deferred. In that case, the module is marked as loaded
only when the deferred is resolved, and its value is equal to the resolved value.
The module can be rejected (unloaded). This will be logged in the console as info.
Remove if_dom_contains from the website, the modules return a rejected deferred if
the DOM doesn't contains the seleted values.
