Default out-of-the-box support for downloading MS office attachments on all servlet containers

  <!-- MS Office mime mappings. We add these to provide out-of-the-box support for downloading Office files as
       attachments. This is for convenience as this is normally a Servlet Container set up but some containers
       do not have these defined by default. For docx/ppt/xlsx this means they will be recognized by IE as zip
       files. See http://littletechthoughts.blogspot.com/2009/01/ie-changes-docx-xlsx-pptx-to-zip-while.html
       for more details. -->
