Since commit 8ac1c19fac7615fecd51e670f798d13158a4e53c the odoo brand primary color
changed, which also changed the color of tips. The problem
was that they lose a lot of contrast in the appswitcher.

  - Before it need a tap to show options
  - And Tap area was not enough for mobile

Since the library nestedSortable was updated to the release 2.1a,
at the below revision:
https://github.com/odoo/odoo/commit/aa19d9edd02756d87056a44340e36568b3183e21
It was no longer possible, in the front-end, to move the menus:
Re-sequence them, put one below another, ...

Indeed, in that piece of code, `.item_id` was never
set with the new release, while it was the case with the former one.
We replace with `.id`, which looks like to have the same behavior.

[FIX] hr_attendance: get group via xmlid instead of searching via name match (which will not works in other languages)

couldn't find a group after rename. -> renamed

- improve some help messages
- improve comments
- small refactoring
- add category to group "Manual Attendance"

for coherence with menus (that got renamed after code was written) to improve
code comprehension.

Also, attendance is an application.

As the field is not shown in the view, it is just done
because the field is still there and easy to do.

As the finished move or the one after might automatically split into its components,
it is not a good idea to select a Phantom BoM for a production order, so
this is for the moment, the best way to avoid it.

[FIX] mrp: when posting inventory in mo, don't allow to pass stock.move.lots with quantity done > 0, but without lot

It is good to have this check, otherwise
it risks taking whatever lot or creating
a piece without lot if you would by accident
say you did so many quantities but no lot was given.

Before this fix, the link was always present, even if no acquirer payment was configurated to allow tokenization.

Stay coherent with others buttons from eCommerce.

Old terms feature display the default terms from company.
But if you have more than that 10 words, it was just unusable.
Now, we just add a link to a page.

The payment method and pay now button was not in the left part.
So if we only have one line in cart, a big margin top was visible.

Company Screen menu was renamed to Kiosk Mode.

This commit renames the associated setting.

When receiving new mail (not replies) to an alias we should not take
case into account.

This also homogenize the treatment of local parts.  For instance, lines
967 and 980 convert the local part to lower case to avoid
case-sensitivity issues.

Also `mail_alias` normalizes alias names by lowering case and finding,
if necessary to make it unique, a suffix to alias name provided.

From RFC 5321, section 2.4:

  > Exploiting the case sensitivity of mailbox local-parts impedes
  > interoperability and is discouraged

Closes #334
Closes #13037

Commit 9676ceec 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.

mass_mailing snippets contained links to "/page/contactus", url which
only exists if website is installed. Also, t-if="website" which were
in snippets were unclean.

Now, the website_mass_mailing module which was already there to install
website snippet and which was already in auto-install with website and
mass_mailing is also in charge of extending mass_mailing features. It
extends the snippets to add the parts which were marked with t-if
website and add the links to "/page/contactus".

The analytic account of the write-off move is not copied on the line
when doing a reconciliation.
