22299	Wizard storage should delete temp files when reset	Simon Charette	nobody	"In order to keep reference to files uploaded through forms during a step submission files are temporally stored using the declared `file_storage`.

[https://docs.djangoproject.com/en/1.6/ref/contrib/formtools/form-wizard/#wizard-files As documented], those temporary files are never deleted, even upon wizard reset or completion.

I understand that it's not possible to clean temporary files in all cases (i.e. incomplete wizard) but I think we should try to cleanup after ourselves when possible. That is when `storage.reset` is explicitly called.

Attaching a PR with a test and a documentation admonition."	Cleanup/optimization	closed	contrib.formtools	dev	Normal	fixed			Ready for checkin	1	0	0	0	0	0
