tui: 'g' + a letter searches list rows

The goto prompt decides on its first key: digits jump to a row number as
before, any other printable key searches the row texts of the list or
menu (case-insensitive, also åäö), with up/down stepping through the
matches. Keys typed into the prompt no longer reach the screen's key
hook, and Enter in the action menu closes an open prompt.
