[FIX] website_sale: yet another kdiff3 mistake during fwd-port 57168a9e

That would break a lot of methods (e.g. using formatLang method).
Closes #8659

Indeed the type field has been renamed to event_type_id. However some code
was still relying on the type and type_count names, instead of event_type_id
and event_type_id_count.

Fix for saas-6 only, don't forward port.

If the user translate a record html field like product... and add block after in English version, the translation doesn't have the new blocks.
In version >= 9.0 the translations contain only textual contents (with font, bold, color...). If a user add a block in english the block appear in all translations (with new text marked to translate).

This reverts commit 07dac79d.

There is apparently a pending PR which will fix this better.

This revision is related to 6f355623.

The above revision had as goal to not allow the partial cancellation
(line per line) of a confirmed bank statement, as it would
prevent the ability to reconcile the statement, as reconcilling
a confirmed statement it not possible.

Nevertheless, cancelling the whole bank statement should be allowed
(using the `Cancel Statement` button), as this cancel all lines
and re-set the statement in draft.

UP and DOWN (keydown event) move the cursor position at begining and end of the input text value. ENTER keypress event add 1 to the cursor position. So these events are now 'preventDefault'.

Since mail.channel user member instead of follower, the frontend widgets required some changes. This commit kind of duplicate follower controller from website_mail for channel member usage. These are now 2 separates widgets. Performance can be improve by removing rpc call when rendering widget, but since this commit is a fix, it does not touch this.

This makes patching much easier. In some cases we can work around some
of these widgets not being exported, but it's ugly and there's just no
real reason to do that.

When displaying ir_attachments, show a preview if it is an image; show the icon otherwise
Clicking on the icon/preview should trigger a download

When converting an opportunity to a quotation,
the note was forced to the `company_id.sale_note`,
which could be `False`.

This prevented the other possible defaults for note to be set,
e.g. the note from the `website_quote` `template_id`.

Besides, the note forced in this wizard:
`sale_obj.get_salenote`
was almost the same than the defaults of the sale.order:
`company_id.sale_note`
except the language, the note translation in partner lang.

Therefore, the default value of `note` for sale.order has been
changed to use this `get_salenote` method, which handle
the language, so it's no longer required to pass it in
the convertion wizard, the note will now be added
as any default value, giving the possibility
to add another note default value.

Add 'force_display' param for the frontend chatter to allow public user to see the textarea. When submitting his comment, he will be redirect to login page (like it was before generic chatter) in both mode (json and post mode). This required changing the error handeling of json mode : when a login is required, the user switch to post mode to allow http redirect, keeping its submitted params (rating, comment, ...).

[FIX] website_sale : avoid to force displaying rating on chatter of other model than product.template

If no value given for the widget, use the default ones for the rating. Otherwise 'NaN' is sent to the server, causing crash in website_sale when posting a comment without rating
