Also minimise activity hurricane by calling expand directly.

Open Orders are searched using indexation timestamp, which allows to see them
in "windows", and does not repeat expand if not needed.

Generate activities and allow to pass the tag. Use search and activate
everywhere which will allow to walk through objects without killing the cluster
even in case of really big documents.

Avoid calling isDivergent which can take few minutes to finish.

causality_state comes from well designed causality workflow, which informs
enough about delivery state. Fetching causality_state property is extremely
fast.

Notes:

Do nothing on 'calculate' instead of disabling *_causality_interaction_workflow as
these interaction workflows do not generate activities directly, and do work
that can't be postponed.

By contrast, 'calculate' transition of delivery_causality_workflow is modified
so that no 'updateCausalityState' activity is created by default.

This commit also update list of method_id which should not call calculate_causality

Because stop date gets the start date by acquisition when no stop date is set,
scripts need to take special care that the date is actually set. This was not
the case in this script, so assignments with only a start date but no stop date
where not considered.

This was especially visible in Base_getDialogSectionCategoryItemList which is
used to select the group in user preferences and in reports dialogs

 - fix "numeric" which was not working at all
 - remove the link to captchas.net
 - ~~partial workaround for the problem that sessions are not shared by zopes~~ dropped, because nexedi/erp5!1451 fixes the root cause

This is horrible user experience on mobile, user can accidentally touch the
image and then get redirected to captcha.net website which is generally not
useful. As far as a I understand their conditions of use, they don't require
use to make a link to their website.

It seems this never worked, it was comparing a string received from the client
with a number from the session.
