Same change in several areas where translations existed:
- website editor notification popup
- elearning share popup
- forum remediation filter popup
- event registration attendees popup
- portal rating popup
- stripe payment error popup
And many other locations where there were no translations yet
"×" has been replaced by its UTF8 character.
Also introduced aria-label where missing.

Before this commit the close icon was included in translated resources.
For example, in Spanish the "×" had been turned into "&veces;"
thus not rendering an icon anymore

After this commit the close icon is not a translated text anymore and
remains an icon across all languages

1) Avoid the storage of all country flags as ir_attachment (230+
ir_attachment in a new db) to reduce the filestore of databases.

The country flags are nearly static and not expected to be modified on
Odoo instances.

This change is based on the new "image_url" widget logic (see previous commits).

2) Extend the flag coverage for countries

Add the missing country flags & specify a mapping to provide flags
for overseas administrated countries/territories.

Unfortunately, this feature revealed a new batch of flaws in the
editor widgets system so some hacks were made to make it work. We will
always have the time to improve the pure technical side later.

This commit also separates the notion of color filter from the notion
of parallax. A color filter can now be applied independantly, when
there is either a background image or a background video. Applying a
color filter on top of a background video is actually a new feature.
Applying a color filter on top of a background image is actually now
achievable by two different ways: this new color filter layer or by
applying the color transformation on the image itself via the related
option. Depending on the user case, both could make sense at the same
time, but more importantly: having a CSS color filter is useful for
using those for default Odoo content (e.g. like the current contact us
page where we use a cover banner with an image with a black filter on
top of it: doing that without CSS color filter would mean to alter the
image directly which would not be ok when the user changes the image).
Also, sometimes you want the unfiltered image on a page and the exact
same one but filtered on another (for example: forum images).

Note: this commit also "fixes" an issue: the optimization feature for
images when parallax was enabled was not available before.

Deprecate alpha, beta, gamma, delta and espilon color names and now use
a new color system: o-color-x, with x from 1 to 5.

This will allow to review the colors of all themes to have nice visuals
for the new color combinations classes, without breaking the current
uses of bg-alpha, alert-delta, etc in current websites of customers
(by keeping the old color and classes for compatibility).

This will also allow to uniformize all themes under the same conventions
to enforce BS color override:
- o-color-1 used as primary (as before, for alpha)
- o-color-2 used as secondary (as before, for beta)

Before, some themes were not following the 2 guidelines. The users
using those themes will simply have the possibility to choose o-color-1
and o-color-2 colors accordingly to restore their website without
breaking the new system features.

Another change is that those colors are defined through color palettes
and not theme color palettes. This will avoid them to generate automatic
bootstrap classes which we don't want (alert, btn) and generate the one
we want by ourself.

Note: for mass mailing, the colors and classes also have been renamed
but the system stays unchanged.

This commit adds new features and corrects some others in the frontend
of website_forum app.
- In the "about" section of a forum, use the s_accordion instead
  of a custom one for the first 3 elements, the last one is on a
  new page accessible from a link below the accordion
- Cut the description after a specific amount of characters in the
  page where all forum are listed
- In that same view, create options that show the number of post
  and the last post a forum has. Create an option to render forums
  in list view
- Allow the user to cancel his vote (down or up)
- Hide the answer box in the post view. Make it appear when the user
  click on the "answer" button
- Use a JS public widget to validate a Post form (new, save, comment)
- Enable the modification of a forum's image from the frontend
- Hide Solved/Unsolved categories in "Discussion" forums
