Org ODT exporter patches (released under cc0)

I am releasing a bunch of local changes that I have in my workarea under
the CC0 license.

I am hoping that this will enable the Emacs project manitainers to slap
GPL on top and distribute these files as part of GNU Emacs proper and
GNU ELPA.

I am not interested in signing any paperwork.  Otherwise, I am willing
to do whatever is necessary to have these changes incorporated.

----------------------------------------------------------------

Special requests:

I want two files authored by me to distribute from GNU ELPA (and not Org
contrib). 

1. ox-jabref.el (part of the patch, also included separately)
2. ox-freemind.el (part of org contrib dir)

----------------------------------------------------------------
