Package debian archive key

After searching for an example I took https://anonscm.debian.org/gitweb/?p=pkg-exppsy/neurodebian.git to create this patch.

This needs more though and testing though.
Adding aegir-archive-keyring as a dependency will stop some auto-upgrading systems.

Maybe depends should be suggests...

Setting up aegir-archive-keyring (3.11) ...
Warning: apt-key should not be used in scripts (called from postinst maintainerscript of the package aegir-archive-keyring)
Warning: 'apt-key update' is deprecated and should not be used anymore!
Note: In your distribution this command is a no-op and can therefore be removed safely.

Based on feedback from anarcat I removed the .postinst part of the patch. and Renamed the key.

But installing this doesn't actually install the key to etc/apt/trusted.gpg.d ???

Anarcat helped in irc .. this should to it. Combined with a sources.list version like deb [signed-by=/usr/share/keyrings/aegir-archive-keyring.gpg] https://debian.aegirproject.org stable main

I'm working on the http://www.aegirproject.org/ getting startted instructions in
https://github.com/aegir-project/aegir-project.github.io/pull/4/files

I've committed this now to the provision git repo.
This should make it possible to test it using our unstable .deb repo.

Steps to test:

• Install the aegir-archive-keyring package from our unstable debian repo.
• Follow the new instructions suggested in https://github.com/aegir-project/documentation/pull/43/files
• validate that you keep getting updates

I've now merge the two mentioned pull requests so http://www.aegirproject.org/ is now updated.
