Commit 929ac90a and 0de0acb3 use the text editor from `app.officejs.com`. Which is not same domain as the main application. When Selenium tests run with Firefox. If Firefox visit a page which contains an iframe from another domain, it is unable to redirect to another link and complaints `Permission denied to access property "href"`. In order to make the test get pass on the server with FIrefox. Revert the changes the that two commits which described above.

This reverts commit 6e58cc8f.

This was freezing some processes on test nodes. I revert during
bug investigation.

In some cases, a Person.password could be a string instead of
None or PersistentMapping. If string, the code was raising
TypeError.

This reverts commit 9befc11a

Moved the SystemPreference_viewHumanResource form to the erp5_hr template so it is available in other erp5_hr based business templates.
