Title: Feature/friendly cmd

This branch a few things (should have split them up into separate pull requests ... eh).

1. Makes `gitmap.py` executable with venv/bin/python as the interpreter in the hashbang
2. Uses more Pythonic import statements by splitting most of them onto separate lines
3. Shows a friendly message when environment variables are not set
