* web_editor, website, mass_mailing
This menu allowed to scroll to the snippets sections by clicking on
their corresponding icons. It was useless as the sections are not
taking a lot of height. This also appeared buggy as clicking on the
last icon highlighted only the second one as this second one was still
the first section visible on the screen when the last section was
fully visible.
This also added fours buttons to the interface which contains already a
lot of them. Now this is replaced by a title "Add blocks" which makes
the editor cleaner and also improved the performance to enter the edit
mode.
Before, the whole editor UI was redefined for web_editor, each
mass_mailing template, website builder, ... Now they all inherit
from the web_editor one.
Difficulty for the user to understand how to change the images.
Some options summernote being in the bar and the other in the snippets editor.
Need to merge this options.
