By default, tesseract runs on 4 CPU and this can be controlled by
OMP_THREAD_LIMIT=1 to run on only one CPU (as documented on
https://tesseract-ocr.github.io/tessdoc/FAQ.html)

In ERP5, we tend to use one zope node per CPU, so we don't want each
of these zope nodes to spawn a process which will run on 4 CPU.

In a quick benchmark it's not slower, even a bit faster to disable threads:

Fixes [#20210517-960A47](https://erp5js.nexedi.net/#/bug_module/20210517-960A47)

The most important changes are:
 - coding style is enabled again for workflow scripts and starts to be enabled for ERP5 Python scripts
 - monaco editor support for workflow scripts, SQL methods and .less
 - small fixes for python/workflow scripts forms and ZMI

See merge request nexedi/erp5!1422

Changing state directly in Base_contribute was only functional for the case
where metadata was discovered asynchronously. In the case of synchronous
discovery, the state was first changed state, and Document_convertToBaseFormatAndDiscoverMetadata
was executed - but this this was causing Unauthorized like this:

      Module script, line 10, in Document_convertToBaseFormatAndDiscoverMetadata
      - <PythonScript at /erp5/Document_convertToBaseFormatAndDiscoverMetadata used for /erp5/document_module/163>
      - Line 10
        return context.discoverMetadata(filename=filename,
    Unauthorized: You are not allowed to access 'discoverMetadata' in this context

because once we have already changed state, regular user no longer have
permission to access discoverMetadata, because that method needs ModifyPortalContent
permission.

Instead, of handling publication_state only in Base_contribute, treat it
like others user input parameter and change state during discovery.

Tests were also re-organised to move Base_contribute related test in testIngestion
and also to run Base_contribute tests as a non-manager user.

This was never supported, we support only [state in $workflow_id]

      ]
    )

using:

    msgattrib translation.po --no-fuzzy --translated -s --no-wrap -o translation.po

translated_title is used in listbox search columns, so it's very confusing
for users if they can not use the usual % character for partial matches.

This changes the behaviour of translated_title to autodetect the presence of
% and use LIKE comparison operator in such case.

these ERP5 Python Scripts were not covered by coding style tests

This ERP5 Python script was not checked until now, and add wrong indentation

The ID is calculated from reference, showing reference is enough.
There is no "callable_type" property on workflow script

Don't hardcode a few roles, use the API to get all roles

Only zope Python Scripts were checked

the convention is to use a my_ or your_ prefix

This is only supported in monaco editor

use syntax highlighting for SQL language, not really correct because of
dtml, but probably better than plain text

 - fix order of ZMI tabs to make `Edit` the default
 - enable ZMI code editor
 - add an icon
 - fix links to python scripts in BusinessTemplate_getPythonSourceCodeMessageList

this field did not use a (my_ / your_) prefix

See merge request nexedi/erp5!1419

with previous implementation, categories_list=[...] could be included
and it would delete existing categories not included in it

So use getPropertyAndCategoryList instead of propertyIds,
that should return a cleaner list for input_parameter_dict here

2 letters code as reference, 3 letters codes as codifications

When viewing the worklist page, a request is made to traverse portal_workflow,
which translate global worklist actions including the document count.

The non regression test was failing with:

    [u'Draft To Validate (1)'] != ['Draft To Validate']

and in real usage, several messages were added to Localizer.

We should not show a link to jump to workflow configuration to end users, these
are not relevant to them and can only cause confusion.

Some erp5 view action use a TALES expression to be visible only in draft state.
When validation a workflow transition dialog, ERP5JS tries to go back to the previous view which is now hidden.

In such case, switch back to the default document view.

Do not return wrong content type
