Now both ascending arrow and descending arrow are displayed in title column and user can sort in specific order explicitly. User also can sort multiple columns by click without using sort-on-dialog.

Otherwise, we use superclass' __contains__ implementation, which uses
objectIds, which is inefficient in HBTreeFolder2 to lookup a single key.

This commit reverts fdf4fa44 that does not work in reality.

Provide migration ability from persistent Control Panel if present.
Drop destructive "backward-compatibility" code (delete object if old
version).

Revert "Change listbox to get the start_date from movement because the start_date is updated when the object is created.

Test were moved to RenderJS's repository.

This runTestSuite uses "python setup.py test" to launch the tests at
a certain folder.

The runTestSuite can upload results using TaskDistribution.

This code is generic enough to be used by others libraries.

The code on ERP5TypeTestSuite is preserved for backward compatibility for
now, until it got updated.

Update now, force the reload of all alarm promises.

Ser periodicity_hour to 0 in addition with "everyday" frequency

Instead raise an exception, try..except to log incapability of resolve the algorithm

Update copyright, license and xml changes on erp5_workflow business template

This exception is required to be used in ZODB due erp5_promise.

The UI created use "Check Consistency" Name in other to keep compatibility with future implementations which are going to use Constraints and checkConsistency API.

In other to keep the promise, create an System Preference if no other were setupped.
