Make `erp5_configurator_standard` use `erp5_configurator_standard_categories`.

Since this is the business templates for standard (SME) configurator categories,
it seems logical to install this business template when installing SME configuration.

Before these changes, standard configurator was using a spreadsheet ( `standard_category.ods` ) to define the categories. Now this spreadsheet is almost empty, it only contain group and site that are custom and the configurated instance will install `erp5_configurator_standard_categories` business template.

The main goal was to make generated configuration use unit conversion module instead
of the obsolete quantity properties on quantity unit categories, but I thought it would make sense to use this `erp5_configurator_standard_categories` business template that is otherwise not used.

if for some reason an ERP5 document has some control characters in title of
description and is exported in ODS/ODT, the export will fail with an etree
error like this:

    XMLSyntaxError: PCDATA invalid Char value 20, line 228761, column 21 (line 228761)

This is because XML does not accept the full range of characters, there are a
few characters that are not allowed.

To prevent these errors, we replace these invalid characters by an error
character (�) before manipulating the XML with lxml.

We use to have consulting_configurator_sample_categories.ods and
standard_category.ods . standard_category.ods was more complete, it contained
standard_category.ods that was missing in
consulting_configurator_sample_categories.ods .

Now standard_category.ods no longer contain "standard" categories, these
categories are now installed by business template, so update
consulting_configurator_sample_categories.ods to the content of
standard_category.ods with all categories (ie. before remove them all in
5e0091a6cbc6ee9d1495e22c0076b0209edada47 )

Use same spreadsheet for all consulting configurator tests

When there's only one quantity unit in the group a conversion group, one
definition is needed (this might be a bug).

Instead of using a spreadsheet for categories, use
erp5_configurator_standard_categories business template.

This business template also configures quantity unit definition in the
new way and no longer use obsolete way of setting quantity property on
quantity unit categories.

The included spreadsheet is still used, but all categories except group and
site have been removed, it now only contain group/my_group and site/main.

Some configurator profiles uses a spreadsheet to define categories
(consulting configurator), some use a business templates.

For the ones using business template, because the categories are not available
yet we have the values directly in the script.

from erp5_configurator_standard/standard_category.ods

from erp5_configurator_standard/standard_category.ods

trade/order trade/discount and trade/tax were only in
erp5_configurator_standard/standard_category.ods

It seems that with ${here/portal_url} returns the ERP5 url , for example http://nohost/erp5 instead of

http://nohost/erp5/web_site_module/renderjs_runner/

Since a89afa43 (Formulator: Support disabled items in all ItemWidget subclasses., 2014-04-02) we can include disabled items in listfields.
This was used for example in erp5_crm to show the services with their hierarchy as disabled items and was useful to display the hierarchy.

In some fields, we don't want user to select "nodes" categories, but only select "leaves" categories (ie. select the most precise category).
This always had a problem when using "Indented title" as display method for categories, because the user can not see the actual hierarchy. This is about making it possible to display hierarchy of categories in this case where we select only leaves, so that it displays like this:

![screenshot of a category with disabled items for hierarchy](/uploads/0f3e8ef68ab6e2ec424e4e8d42fc5e2a/image.png)

This required to:

 - introduce a new category API, `disable_node`, which is semantically very close to `filter_node` except that instead of filtering out node categories that are kept with `None` as related URL. Symmetrically, we also introduce `disable_leave`
 - make `ParallelListField` support disabled items. Even if this was properly supported in underlying fields, some parts in `ParallelListField` did not differentiate between `None` and `''`.
 - modify several forms to use `disable_node` instead of `filter_node`

See merge request nexedi/erp5!1199

For PDM/Trade we use:
 - "Site" for node category
 - "Warehouse" for node
 - "Owner" for section category
 - "Owner" for section

For Invoicing/Accounting this does not change.

Also, since in PDM/Trade context we are sometimes only taking care of physical movements/quantities and not the ownership, make sure that:
 - "Site" is first in report dialogs
 - "Section Category" is not initialised from preference, so that reports show the quantities in a location regardless of the ownership

- add an empty item to the list, so that user have to choose something. The empty item was missing here:

![image](/uploads/5be3e9d5acf1233270516c7463dbfdd4/image.png)

If there's an empty item and we force user to choose, there will not be the problem that user can forget to select the good value and mistakenly generates for the Fifo because it's the first value.
