Add offline storing of inspect forms.

This allows the inspect form to be submitted when offline, with the data
saved in localStorage, the number of saved forms shown in the banner,
and the forms to be uploaded when back online.

It copes if you go back to a report after having submitted the form, and
if the back-online submission fails due to CSRF failure, retrying once
with a new token.
