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.
