Support for Flat OpenDocument

[Cédric Krier]

Hi,

I have finished the patch to support Flat OpenDocument. You can find it
at https://relatorio.tryton.org/bug26.
The support is transparent because it convert on the fly the flat to
standard zip.
It will be great to have test results from many different kind of
templates because the transformation is mainly based on interpretation
of the format so we could have missed something.


Side note, the major advantage of this feature is to be able to use
plain text file as template so it is easier to manage in VCS.

Thanks,
