1.18 docs

[Nick Veitch]

Denizens of the Jujusphere!

With the 1.18 release of Juju came loads of new features, and thanks
to some outstanding teamwork we managed to document pretty much
everything already!

So, if you want to:
* Configure proxies for your environment -
https://juju.ubuntu.com/docs/howto-proxies.html
* Manage your SSH keys - https://juju.ubuntu.com/docs/howto-authorised-keys.html
* Backup and restore your bootstrap environment -
https://juju.ubuntu.com/docs/howto-backup-restore.html
* Set up simplestreams for a private cloud -
https://juju.ubuntu.com/docs/howto-privatecloud.html

or simply update yourself on syntax changes for local provider
(https://juju.ubuntu.com/docs/config-LXC.html) or how to dest^h^h^h^h,
ahem, remove things
(https://juju.ubuntu.com/docs/charms-destroy.html), you should check
out the new docs.

As always, if there are errors or omissions, ping me or file a bug
(https://bugs.launchpad.net/juju-core/+filebug)
