Improve tox configuration (#68)

* Improve tox configuration

Drop `python setup.py --quiet clean develop`. tox installs the package
by default automatically. There is no need to do so explicitly.

Add `skip_install` to the lint environment. There is no need to install
the package to do static analysis. Slightly speeds up the command `tox
-e lint`.

Add `minversion = 1.9` to support the `skip_install` option.
