[gnome-system-tools/users-ui-redesign] Add convenience function users_table_get_current()

[Milan Bouchet-Valat <milanbv src gnome org>]

commit 8dedf41511073fc6c0cab3272b7da8aba7876775

    Add convenience function users_table_get_current()
    
    This function returns the current user, which is the first selected user from the table, and the one whose settings are shown. It's now used from on_table_selection_changed(), which will now display the settings for this user if several users are selected, instead of merely skipping.
