Support different Metadata Layouts with Templates

[davidak]

I have a Wordpress Blog and want to export to a StaticSiteGenerator. (don't know which one yet)

Some of them have an import integrated, like Nikola (which currently don't work), but why do we always reinvent the wheel if this tool works?

We only have to support all the different metadata formats.

I would suggest to use Jinja2 templates but i think supporting Mako (later) also is not hard.

If we have the templates someone can also write a converter so switching the Generator would also be possible.
