feat: add --version parameter to cli (theskumar#114)

venthur · theskumar · commit 69735cf037eb · 2018-07-11T16:06:24.000+05:30
* Added support for --version

the actual version is now stored in dotenv/version.py and setup.py reads
from that instead of the hardcoded variant.

* Updated bumpversion.cfg to point to dotenv/version.py

* Make flake8 happy
