Issues on latest version of the docs

http://docs.ckan.org/en/latest/

Looks like RTD is for some reason loading the latest version of the sphinx-theme-okfn submodule, although on master we are pointing to a specific commit.

https://github.com/okfn/ckan/tree/master/doc/_themes

Rather than trying to fix it on RTD I think is worth upgrade the theme anyway. I tested the docs and everythng seems to work fine, images, search, autodoc, etc, except for the logo.

The button on the bottom is not showing the versions for me on Chrome but that looks like is a RTD issue:
