* update template tool configuration
* create working copy
* create skin folder

Add a gadget to display and select the list of changes.

The gadget will show the selected diff to change the selection if needed.

Changelog can also be directly entered in the gadget to quickly switch the view while writing it.

Use usual ERP5 page template to commit bt5 changes from ERP5.

Use an hidden field to propagate all needed input values in case of an exception.
This single field will keep a json value, to simplify the maintainance of all forms using it (instead of many string fields).

Stop accessing the REQUEST directly, and rely on ERP5 navigation scripts (like Base_redirect) instead.

See nexedi/erp5@ea219b74

If enabled, accessing the 'View' skin selection will raise an Error.

2 alarms are provided to automatically enable/disable xhtml style for some period of time.

Some users can be always continue using xhtml style.

in c361a8c3 (erp5_pdm: improve product invividual variation, 2020-03-09)
we changed to allow default images in product individual variation and modified
IndividualVariation_view to add a file upload field to upload an image, but this
form is shared with other individual variations portal types.

Without setting the default image property sheet and allowing Embedded Files as
sub-documents, saving the form was causing an error.

Possible services depend on the selected project.

If we only refresh this list when user selects another project, we don't
support the case where there's only one project available for user, because
the list of services is the default one, not the one filtered for the
select project.

Now that we have an empty item, we should make sure user selects something.

If we have more than two options to project and resource

RSVP.Promise cancel callback do not expect a Promise as result.
In order to handle potential errors triggered by setButtonTitle, run it in an renderjs's job.

We no longer run tests with `python setup.py`, but simply with `python -m unittest`

With nexedi/slapos!862 we no longer need this

No error in testCMFActivity and testConflictResolution.
For the only error in testInvalidationBug, see comment.

But this commit is not enough for ZODB5. The only known issue so far
is the use of newer pickle protocol, which breaks export of ZODB data
and requires non-trivial changes in our XMLExportImport/ppml code.
So for the moment, many failures in testBusinessTempate.

erp5_web_renderjs_ui_test: reproduce validation error issue and add asserts to make sure field has expected class

* Trigger focus and blur to test renderjs functions properly
* Add asserts to make sure we don't lose value after raise Invalid Date
* Cover issue that invalid class does not disappear after click to create new object Foo in relation input
* Make sure fifth_failure input has invalid class
* Cover validation error to multicheckbox, checkbox and radio fields

* change the label field to not display the error text by default
* change all html5 fields (input, select, textarea) to add a custom *invalid* class when the field is invalid
* change all html5 fields to listen to the `focus` and `blur` event (with the renderjs onEvent method)
  Then, acquire (with `declareAcquiredMethod`) and call `notifyFocus` / `notifyBlur` methods respectively.
* change the label field to handle `notifyFocus` / `notifyBlur` (with `allowPublicAcquisition`).
  Change the validation error text display state depending on the field status
* Trigger onStateChange to set invalid class. If error comes from input field, we need to change state locally to set invalid class
* Regenerate gadget_erp5_nojqm.css from  erp5less.css using http://lesscss.org/less-preview/
* Textarea gadget should not prevent default when invalid event is triggered
* Support notifyFocus and notifyBlur in panel

Users with only view permissions in accounting should not be offered to use
the grouping reference fast inputs, because grouping transactions is a kind
of modification.

Listbox title is automatically translated, calling translation explicitly
is wrong here.

erp5_officejs_support_request_ui does not yet supports translation fully,
but we start testing translation.

For now only home page and panel are covered.

For the need of this test:
 - depend on erp5_l10n_fr because we'll test in french
 - modify test service so that its title is translated to french (and depend
   on erp5_content_translation for easier management of these translations)

Resource reference can be useful for example with cases where resource
titles are not uniques, or when some classifications are codified in
resources references.

crm/officejs_support_request_ui: use "resource__translated__title" as Support Request Type in listboxs

In other places, we always show the translated service titles.

By using resource__translated__title, this enable the new syntax for
translated related keys from aee8bcac (ERP5Catalog/content_translation:
support translated related keys, 2020-10-07), so that column can be searched
or sorted.
