Flake8 was nitpicking about:
ihatemoney/forms.py:192:13: F841 local variable 'e' is assigned to but never used
ihatemoney/utils.py:26:8: W605 invalid escape sequence '\w'
ihatemoney/utils.py:26:10: W605 invalid escape sequence '\s'
ihatemoney/utils.py:27:8: W605 invalid escape sequence '\s'
* Use absolute imports and rename package to ihatemoney
* Add a ihatemoney command
* Factorize application creation logic
* Refactor the tests
* Update the wsgi.py module with the new create_app() function
* Fix some styling thanks to Flake8.
* Automate Flake8 check in the CI.
