------------------

- Do not send task emails to non-employees. We may have a customer as
assignee of a PoiTask. The ticket is assigned to her, but as she is
an employee, she should not get an email that she can work on the
task.

------------------

- Fix longstanding bug in reloading of task-form provider. When doing
a transition on a story, we now refresh the 'add task' part.

------------------

- Added zope.app.content as dependency. Helps for Plone 4.2
compatibility. But Plone 4 is not officially supported yet.

------------------

- Added upgrade step to recatalog the Stories, as their size_estimate
in the catalog was broken when using xm.booking 2.0.
[maurits]

- Get KSS portal status messages translated correctly again in Plone
3. Not used in Plone 4; not sure yet if this is needed there.

- In the employees_overview also list members that are Employee
because they are in a group that has the Employee role. Patch by
Yuri and Mauro.

- In the employees_overview make the Employee name a link to see the
task_overview for that Employee. Patch by Yuri and Mauro.

------------------

- Added Plone 4 compatibility, while keeping Plone 3 compatibility.
May have a few rough edges and has two failing tests on Plone 4
(including one in xm.tracker), so use with care.

- Avoid TraversalError in the xm.tracker when taskbrain2dict throws an
AttributeError for a brain that fails getting its object.
