pylint:
* config files with BOM markers can now be read.
* epylint.py_run does not crash on big files, using .communicate()
instead of .wait()
astroid:

While this makes things a little more complicated and means we'll need to use
`-r` to recreate tox environments, it has several advantages:
- Full support from requires.io (including PRs)
- Workaround for https://bitbucket.org/hpk42/tox/issues/332/ so we can update
virtualenv/pip
