Patch: PDF/A instead of "normal PDF"

[RolfWojtech]

Today one of our customers rejected our invoice and demanded on in PDF/A form ( https://en.wikipedia.org/wiki/PDF/A )

So I took the time to figure out how to output PDF/A in aeroo docs by passing the SelectPdfVersion=1 to OpenOffice/Libreoffice.. The result is the following patch:

             self.document.storeToURL('private:stream', props)

A similar patch works for report_aeroo_ooo/DocumentConverter.py

I am not sure if I will find the time for a proper pull request for this feature, especially because Aeroo Docs as a generic server cannot really output PDF/A by default. However for use in conjunction with OpenERP/Odoo, PDF/A clearly makes more sense and I wanted to share this in case somebody else needs it or maybe alistek wants to include the idea one way or another
