    user-panel: add UmPasswordDialogMode enum instead of using numeric literals
    
    The um-password-dialog combobox has a column in its model associated
    with what password action to apply. Possible actions are:
    
    - Normal password
    - Set password at next login
    - No password needed
    - Lock account
    - Unlock account
    
    These actions are currently represented in the code with harded coded
    numeric values (0-4).
    
    This commit cleans up the hard coding to use a symbolic enumeration
    instead.
