  21  * @brief User management for Disobedience
  22  *
  23  * The user management window contains:
  24  * - a list of all the users
  25  * - an add button
  26  * - a delete button
  27  * - a user details panel
  28  * - an apply button
  29  *
  30  * When you select a user that user's details are displayed to the right of the
  31  * list.  Hit the Apply button and any changes are applied.
  32  *
  33  * When you select 'add' a new empty set of details are displayed to be edited.
  34  * Again Apply will commit them.
  35  *
  36  * TODO: it would be really nice if the Username entry could be removed and new
  37  * user names entered in the list, rather off in the details panel.  This may
  38  * be possible with a sufficiently clever GtkCellRenderer.
