Title: DOC: add old version warning

This extends the sphinx theme to allow a setting in `conf.py` which when set to True, adds a header at the top of each documentation page warning that the documentation is an old version. I think we should cherry-pick this into the older versions. This way, if google directs people into old docs, there will be a prominent warning on every page.
