tools, frontends, memory: param definition and XMLUI handle multi-selection for list widgets:

- we need to update urwid_satext to revision 79
                          - no more "value" attribute value in the "list" element, use
                            HTML-style "select" attribute in the "option" elements instead
                          - /!\ param saving do not handle multiple values yet!
