Allows overriding it on instances where the invariant
  grouping_reference IS NULL == grouping_date IS NULL
is applicable, allowing simpler query execution plans.

For type checking (not recommended, but sometimes useful).
Expose it as BaseQuery, to avoid conflict with AutoQuery original name.

Make it more easily extensible by exposing a callback.
Stop loading documents in the simple version that are only needed by the
detailed version. Also, stop checking for this inside the main loop, and
instead use the callback mechanism.
Use a single query to look for mirror section title instead of one per
mirror section.
Behaviour change: mirror section (ie, the entity) title is not
translated anymore. It used to be because there did not seem to be a
reasion not to. It is not anymore to avoid loading rach entity from ZODB
in the default report. This rework makes customisation easier, including
overwriting this untranslated title with any desired transformation.

[erp5_xhtml_style] erp5.css: Set a margin between Save button and the block of tabs, then Save button does not overlap with tabs.

This allow to go to dialog page on a module, and keep the search parameter.

SearchField: keep the last full text parameter editable
Allow to focus on a specific input
Searchfield: use an hidden field to store the parsed value (to simplify test code)
Display full text queries as much as possible in raw format

This will prevent the input gadget to be changed if its parent call render with the same value (as ERP5 does in case of formulator error).

The typical use case is to go to a module from a worklist link.
This leads to a complex query to display only the matching documents.

Opening the filter panel should not lead to lose the query.
User must be able to add extra parameters to this query thanks to the filter panel.

This was done by:
* changing the DOM only in the changeState method
* handling unexpected search expression (not parsable, complex one, unknown column, ...)
* improving query operator support
* dropping not needed HTML element attributes.
* adding tests
