Subject: [PATCH] chore: allow app store distribution through an AGPL
 additional permission

App store terms put limits on recipients, such as device caps and DRM,
that section 10 of the AGPL does not allow, so a Bulwark app built from
this code could not be shipped through the Apple App Store or Google
Play without breaking the licence. The mobile app reuses the webmail
locale catalogs and several ported modules, so the permission is needed
here as well as in the native repository.

Add a section 7 additional permission that allows app store
distribution as long as the source of every shipped version is public,
free, linked from the listing or the app, and not further restricted.
The README licence line and CONTRIBUTING.md now say that contributions
come under the same terms.
