[Qgis-community-team] 2.18 & Python3 for website

[Richard Duivenvoorde]

Gents,

I'm currently upgrading the html-docker image that we use for building
the website and documentation.

I've now a new image qgis/sphinx_html_3, which is:
- based on latest Debian stable: Debian Stretch (was Jessie)
- python 3
- sphinx 1.5.2 (for now) which would make it possible to mix rst + markdown

Website seems to build fine, so I think I'll change scripts there and
make Website use that machinery.

Next step would be:
- see if documentation html is building ok with this
- harder: see if pdf is still building ok with this

I'll try here locally with current master (== docs for 3.0).

But was also wondering what plan was to release 2.18 docs?
I do have some time free now, to do this.
I think it is best to leave those builds on the old Docker images anyway.

Regards,

Richard
