/** @file disobedience/users.c
 * @brief User management for Disobedience
 *
 * The user management window contains:
 * - a list of all the users
 * - an add button
 * - a delete button
 * - a user details panel
 * - an apply button
 *
 * When you select a user that user's details are displayed to the right of the
 * list.  Hit the Apply button and any changes are applied.
 *
 * When you select 'add' a new empty set of details are displayed to be edited.
 * Again Apply will commit them.
 *
 * TODO: it would be really nice if the Username entry could be removed and new
 * user names entered in the list, rather off in the details panel.  This may
 * be possible with a sufficiently clever GtkCellRenderer.
