ostree 2012.10

[Colin Walters <walters verbum org>]

http://git.gnome.org/browse/ostree/commit/?id=503535da4838d07f76405b15872261cd9c32f72e

The biggest change in this release is that /etc is now writable, and we do
some basic configuration management.  This has unlocked a lot of things -
for example, NetworkManager can now write out wireless networks to /etc,
and this gets propagated forwards.

The second biggest change is that "ostadmin" is now "ostree admin".

And finally, we've added support for an "archive-z" mode.  I've been
testing this on the ostree.gnome.org build server, and it is a very
noticeable speedup for download time; it involves 1/2 the number of
HTTP requests, and is compressed to boot.
