Release 2015.11

[Colin Walters <walters verbum org>]

OSTree v2015.11 is now available via this git-evtag[1] signed tag:

https://git.gnome.org/browse/ostree/tag/?h=v2015.11

This releases fixes an important regression in v2015.10 where `ostree
commit` would write invalid timestamps.

There is one user-visible change in that `ostree remote refs`
now prints the remote name, for convenient copy/paste.
