Improvement: As proposed by Jean-Paul when this extension was added (2010),
allows mixing left- and inner-join lookups.
Improvement: Now it is not required to specify tested_base_category_list
to enable inner joins: they will automatically be used whenever a base
category set on context matches the preference. If all categories set on
context match the preference, then no left join will be used at all.

This only makes a difference when "test=False" is given, which is a hack
anyway.

The main purpose is to stop calling buildSQLSelector so it can be removed.
Remove Base_zSearchRelatedObjectsByCategoryList.
Also, discard a superfluous comment in testArchive which references the
discarded ZSQLMethod, for consistency.
Fixes an existing failure in testArchive.

Less ambiguous than previous syntax while keeping names short.
Allows defining more flags without limiting base_category namespace: the
only forbidden base_category id is "related", which was already reserved
(ie, not working) in previous syntax.

These improvements include :
   * better address reporting
   * better handling of Social Security Number and Temporary Technical Number
     for foreign employees
   * add more checks and UI error messages to report wrong values to the user
     before he submits the DSN
   * fix bugs for some edge cases

When aggregating Paysheets using a dialog, we don't want to aggregate deleted ones.

* Only process Expense records with a date set (avoid processing records with no data)
* Add garbage collect on empty draft records
* Change jIO configuration to resolve conflict with remote as the reference
* Comment indexxedDB patch XXX code should be added for Safari to use websqlstorage

// XXX Please note this is a work-around to have a usable application
// waiting for a bug in IndexedDB or jIO to be fixed
// this bug can been seen on 'fast' devices where
// data stored in settings is not accessible right after save.
// it was shown that after redirecting to sync page, the
// "sync_reload" value got in the sync gadget was "undefined"
// Hence triggering synchronization and not setting the storage first
// and redirecting once again on the jio configuration page
