v0.16.1 docs
did you merge this? 
 No, this are the fixes I did for the docs, but I just applied this to my checkout of the 0.16.1 version tag for building the docs (so everything in here is in the online stable docs already).  
This is still open for review. If everything is OK, it can be merged. Otherwise I can do a new doc build to update the online docs
 ok, perfect. Everything updated (pandas.pydata.org/PyPI), so sending out ann soon.
