erp5_interface_post contains ***_post_modules, which purposes are to track posts that go out and in ERP5, without any processing.

erp5_pdm: use preferred category child item list method in my_variation_category_list field library.

Python script needs to be recompiled when they comes from a change of
class. This was done when business template was installing scripts, but
not when automatic migration from old catalog to new catalog was done.
So make sure to call _compile directly in changeObjectClass to make sure
Python Scripts would always work after a change of class.

Replace the airplane icon by a search button if not value is set on the field.
This make it more usable on mobile, where it's easier to browse than typing text.

Regression introduced by nexedi/erp5@cf1a0610

getSecurityQuery returns None when caller is superuser. Avoid passing it
to buildSQLQuery, as it would mistake security_query for a column name.

Float fields are needed to round amounts.
Also, discard empty form groups.
Also, make "hidden" the first group, so any created field gets hidden by default
(which is what we want for all listbox "editable" fields).
Also, remove overrides which seem unneeded for report appearance:
- "lines" is not used for OD* rendering
- "columns" is already the same as in original field
"editable_columns" is used in odt (and maybe in ods, unclear), but
inconsistently with its intended use... so leave it, sadly.

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.
