Removed extras

Extras were removed during the tox branch changes, but
somehow the updates didn't make it into the current HEAD
of master. These are being removed for the current time,
since tox now handles lint and test dependencies. Docs
is being left alone, because someone may still wish to
build the docs and see them locally
