Depdending on situation several fixes (f885202, fc8e446) leads to issue
in small screen size:

- in iframe editor with without snippets => the width of the content is
  decreased of several times the sidebar that is not shown

- in editor with sidebar => the content gets behind the sidebar

With this changeset we remove part of the above commits which seem to
fix both issue.

note: this also fixes that the mass mailing content applied CSS should
not depend on screen size, or what is send would differ dependin on
which screen size clicked on SAVE (on last inlining of CSS).

Scenario:

- create mass mailing with icons and without title
- save and get error "The followign fields are invalid: Subject"
- fill subject and save
- edit

=> the icons have disappeared

This is because mass mailing widget is using:

- a "body_html" field that contains inlined html
- a wysiwyg editor to edit field "body_arch"
- a textarea containing "body_arch" value to be saved

When we save this happens:

1. we save the current value of wysiwyg into textarea
2. wysiwyg content is inlined (eg. transforming font in image)
3. inlined wysiwyg content is set to "body_html" field
4. if there:

   - is no error while saving => body_html and body_arch are saved and
     will be used on next edition

   - if there is an error the fields are not saved, and we now have an
     inlined content on wysiwyg, so next time we save the "body_arch" is
     going to be inlined:

     => this for example breaking the icons on edition

Office Outlook doesn't take into account the [style] attribute, and it
doesn't manage width/height in percent value.

This commit set width/heigth attribute in pixels and also always set the
width/height in style attribute (keeping them in the original unit and
setting them to auto if not present).

This is a reintroduction of 2015 commit bdf58adb465b

Before this commit saving a custom snippet inside an email template
produced a "cross origin" error related to the combination of the save &
reload mechanism with the fact that the email template editor is inside
an iframe.

After this commit saving a custom snippet inside an email template is
not available anymore.
Given that fixing the reload problem would be only temporary -while
quite complex-, it has been decided to disable the feature until the
editor allows for cleaning snippets without saving them.

The button text colors were forced to the default link color while that
color should only be forced for links which are not buttons.

Note: this fix will not impact existing mail templates thanks to
transcoding. That's why it is possible to fix safely in stable versions.

Primary and link buttons are "hacked" by mailing themes scss. We thus
have to fix their preview if possible (as they are previewed as standard
bootstrap while they actually have a different look depending on the
mailing theme).

Note: this commit is obviously a big hack which calls for lots of
improvements in master.

*: web_editor

The snippet options which were specific to mass mailing were not loaded
anymore as they were loaded outside of the iframe where the edition
take places. Fortunately, the generic options were still working and
are the most important.

This bug was only revealed thanks to another bug fix which wanted to
be done in the unloaded file.

Note: this fix is a series of huge hack to make it possible and as safe
as possible in stable versions. This obviously has to be refactored in
master, if not already done.

This commit lays the groundwork for the new editor by adding empty files to the assets in
order to change them later on. The new editor is not stable enough to be merged right
now, but delaying it to 15.0 would be problematic as the current editor has many bugs that
we are unable to fix because of how summernote interacts with browser-dependent code as well
as all the hacks that were done on top of it for Odoo since 8.0.

See parent commit for information about the scrollbar moved to the
'#wrapwrap' element, which was necessary to achieve this right panel
design. Note: in the future, having the scroll on the #wrapwrap may
not be necessary anymore as the edition might be done in an iframe.
