Plone.app.users

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

- Update tests. We now check if the user can add and delete the portrait
himself.
[tschanzt]

- Added user timezone selection to user preferences and a dependency on
plone.app.event for vocabulary for user timezone selection.
[seanupton]

- Fixed i18n of new_password field in change-password view.
[vincentfretin]

- Fix email as login validation in the personalize form (UserDataPanel).
This is for the case when email is used as login. It checked that a
changed email address was valid as user id. But the user id is
never changed here, only the login name. We only need to check if
this address is not used by another user.

http://plone.org/products/plone/security/advisories/CVE-2011-1950
[fRiSi, davisagli]

[WouterVH]

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

- Include plone.app.controlpanel configure.zcml because we use permissions
defined in this package.
[vincentfretin]

- Use portal object instead of self.context in AddUserForm so we can easily
subclass the class for another context.
