- Bug 6800
  - Move HTML files used for pop-up window in reactionresponse to
    /adm/reactionresponse directory to support public access.
  - Replace use of &EXT('query.') with javascript to retrieve values for
    reaction, field and id from query string, and replace call to &xmlparse()
    with HTML entity to provide rightarrow.
