Do not access form submission REQUEST from the listbox list method,

This reverts commit 35b2c024.

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>

Changing the language and browsing to another web section require to fully refresh the page.

This breaks the previous gadget API.

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

Catalog seems to correctly handle the OR parameters.

Do not lose the possible external `query` parameter.
