This fix a regression from #316 (scrollbar was displayed all the time).
Note that the padding-bottom value is totally empiric, but proved OK on my Fx
and Chrome instances + some responsive tests. There might be finer solutions,
feel free :-).
* Update to a more flexible admin authentication
* Admin can now access any project
* Add delete and edit options in the dashboard
* Add a link to the dashboard in the nav bar
This is a rework of the changes proposed by @Olivd, so they can apply on top of
the latest master without trouble. All credit goes to him for the code.
* 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.
