Affero notice and source code

[0uep]

When a Garcon-based web application is released under the GNU AGPL, the web application should offer its source to those users in some way. For example, the interface of the web application could display a “Source” link that leads users to an archive of the code. The GNU AGPL is flexible enough to choose a method that's suitable for the specific program. See section 13 of the AGPL for details.
