    log-window: improve icons in the search entry
    
    There are a few improvements we can make to the search entry icons in
    the log window, which this patch tries to fix.
    - icons in entries are usually symbolic in GNOME 3, so I made the icons
      symbolic.
    - I merged the two icons in just one on the right using the shell-style,
      i.e. the search icon turns into a clear action once there's some text
      typed into the entry (Documents also uses the same style for its
      search entry).
