Plugin was broken due to use of deprecated hook/subroutine afterAttachmentSaveHandler
(called by /path/to/foswiki/lib/Foswiki/Meta.pm). Replaced with subroutine
afterUploadHandler and adjusted parameters accordingly. As-is, the plugin will now successfully
convert from .docx/.doc to html and create a separate attachment in html format for each Topic if
configured to use Abiword.

To do: since older utilities are no longer being updated, abiword should be the default.
In addition, still needs to be corrected so that HTML file can be included in the topic text
if desired - this functionality is still broken.
