Print a tree of file names instead of a pretty-printed JSON object.
It is better because the full JSON object can overload the browser.

It contains two modules, Computer Metadata Snapshot and Computer Trusted Metadata.

Computer Metadata Snapshot's purpose is to store serialized (JSON) documents generated by
https://lab.nexedi.com/nexedi/metadata-collect-agent

Computer Trusted Metadata's purpose is to store serialized (JSON) documents generated by
https://lab.nexedi.com/nexedi/software-metadata-crawlers

It also contains a test that can ensure the Contribution Predictate for .metadata files is working correctly.
The intended behavior is that all files that end with the .metadata extension end up within the
Computer Metadata Snapshot module.

Computer Metadata Snapshot has a preliminary view that displays the JSON document in a TextArea.

So that it can be registered properly on load and later added through the ZMI.

ZODB Components: Tool Component: Only validated 'reference' must be considered when registering a Tool.

Otherwise setting an invalid reference will make the Component 'modified' but
try to use that invalid reference to register it and fail.

With chrome ( 85.0.4183.108 but I think it appears a few weeks/months ago )
when using erp5_xhtml_style when the cursor in the first column on the left
it's not visible, because the bold background hides it.

Default user agent spreadsheet is a 2px padding, but we have a rule applying a
padding 0 for all textarea. Revert this rule for textarea used as fields in
content.

## before:

The cursor is in *Description* field, left to "This style is ..." but cannot be seen.

## after:

The cursor is same location (*Description* field, left to "This style is ...") and this time is visible.

Previously this would be rendered as empty String
(unless we had a hidden field to define precision)

Commit adds also testListboxZeroValue in  erp5_web_renderjs_ui_test

Add a new document in the history while trying to show its latest state

Use this command on the module's list and worklist, to come back to the expected page when done on a module.

ZODB Components: There is no need for `description` and `source_reference` to be RecordedProperties.

* Not considered for `modified` state (dynamic_class_generation_interaction_workflow).
* `source_reference` sets only once at import from filesystem.

This implements Products import compatibility based on Component.source_reference
using existing import hooks so that Products.ERP5.Document.Person for example
is importable (actually returning erp5.component.document.Person module).

This only works with non-FS modules (IOW when the ZODB is accessible and
portal.portal_components is available).

This test (just like all legacy filesystem tests) does not use business
template dependencies but just install business templates in the order from
getBusinessTemplateList, but business templates are not listed in correct
order.

It use to be OK (which warnings), but erp5_test_result can no longer be
installed without erp5_project, so review installation order to install
erp5_project earlier.

Tabular Data Tool is a Tool to handle tabular data (2-dimentional table data)
in erp5.
The tabular data type is currently a plain pandas DataFrame. It is intended to
use with ERP5 Reports to create spread sheets (ODS/Excel).

With Tabular Data Tool, we can do those things on reporting:

- transform dict-list, portal-catalog-result and document-list into a tabular data
- joining/grouping/sorting the tabular data
- using vectorizing function to optimise time consuming reports
