Changed local_users_menu() to use the new 'region' feature to place an '+ Add' button in the top right of the header region. Added local_users_add_form_submit() handler, empty implementation. Added local_users_install() to create a 'local_users' local storage key if it doesn't already exist. Implemented hook_device_online() to cancel connection to server. Added local_users_load_users(). Changed local_users_list_page() to show a list of users, but we can't add users quite yet, coming soon.
