Datamanager 2 password widget

This is a simple widget to request a password. It will render two password input fields, whose values need to be identical for the password to be accepted. HTML_QuickForm compare rules are used to enforce this. The value is taken from any valid text type which has a value member, but initialization is always with an empty string, as this widget cannot (and should not) display an existing password. The rule is, that as long as the value is empty, no password change will be given to the caller during the synchronization (effectively skipping the operation).

Available configuration options:

• string confirm_text: The confirm-note appended to the second fields label. This is put through the regular schema translation pipe and defaults to '(confirm)'.
