[WIP/RFC] Bibliography support ODT + JabRef

I need some quick feedback on how this works out.  Look at the Org and
ODT file and tell me to what extent it will suffice.

I am not interested in Org syntax at the moment.  But I am willing to
exchange notes with anyone who wants to "canonicalize" some Citation
support in Org.  For now, the keys are referenced with \cite{key1, key2}

I am dumping

1. messages buffer.  Shows how JabRef can be invoked on the command
   line.

2. JabRef's jstyle and layout files split out from the Jstyle.

   The jstyle is the one that comes with Jabref's OOplugin itself ->
   Default Style (numerical citations).

   The layout files were broken apart from the Jstyle for the purpose of
   org-odt export.  The files may not be perfect but gets the job done.
