Title: Fix version detection (setuptools and distribute)

Fixes #81

The versions of `distribute`, `pip`, `setuptools` and `wsgiref` are excluded from the output of `pip freeze`, however they do show up in the output from `pip list`. This allows us to use a more general implentation of parsing the output from `pip list` to get the current version of all distributions.

Also removes a dependency on `grep`.

Distributions excluded from `pip freeze`:
