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'
For this I had to create an Jinja2 explicit environment, so I put a
function in `ihatemoney.utils.create_jinja2_env(strict_rendering=False)`.
When using this environment and if `strict_rendering` is activated,
templates using undefined variables will now error out rather than
failing silently.
