ostree v2014.7

[Colin Walters <walters verbum org>]

OSTree v2014.7 is now available via your usual git tag:

https://git.gnome.org/browse/ostree/tag/?id=v2014.7

While this follows quickly on the heels of the last release, it fixes an
important memory corruption bug that was hitting rpm-ostree.  Not to
fear - upgrades are still fully safe, it was just crashing on exit when
freeing memory.

Secondarily, I finally fixed an issue with /etc processing that kept
tripping people up:

I'm really grateful to Owen for diving in and fixing some of the --help
processing code, among other things!

Also, let me call out a breaking change, which is the removal of the
"current" symbolic link:
