form_list does not use Base_edit

XXX TODO Formulator checkbox must be modified to not render an input when the field is in read only
Otherwise, in listbox, it creates an input inside a `a` element, which is not valid html

This reverts commit 689e242c.

If user group are recalculated before changing the workflow state, it will only return the same security group

Do not access form submission REQUEST from the listbox list method,
as it is rendered asynchronously in ERP5JS

Allow edition in the new UI

This make everything slow as hell and prevent to quickly save.

Example: <h2 class="foo">bar</h2> => <h3 class="foo">bar</h3>

erp5_web_renderjs_ui: keep previous focus color

Change max age to 1 hour and 1 day

erp5_officejs_support_request_ui_test: wait for gadget_erp5_page_support_request_fast_view_dialog to refresh the select field

We may want to set autocomplete 'off' or whatever other value

Activity distribution (actually: validation) is fundamentally a bottleneck
of the current CMFActivity design: there can be only one distribution/
validation node, and it must check every single activity which express a
dependency over any activity, until these dependencies are satisfied.
As a result, distribution/validation is in the critical path between an
activity being spawned and it being executed, and this work cannot be
parallelised. So care should be taken to waste as little time as possible,
in order to reduce the activity execution latency.

Before this change, CMFActivity would distribute at most 1000 activities
(MAX_VALIDATED_LIMIT) per queue per timerserver wake-up.
In a typical ERP5 setup, timerserver ticks once per second, which means
CMFActivity was unable to validate more than 1000 activities per second
per queue. Maybe there are more activities which are possible to validate
but still the code was forcing the node to sleep until the next wake-up,
which is a tremendous waste of time.

This change fixes that issue by having ActivityTool.distribute keep looping
until there has been an iteration over all activity queues which
simultaneously did not find any activity they could validate. This lets
Zope yield CPU control when it would be better spent processing activities
(those which are preventing the validation of any activities remaining to
validate) without imposing a maximum effective validation-per-second
hard limit.
