[Dev] libretools 20131027 release announcment

[Luke T. Shumaker]

I just pushed libretools 20131027 to [libre].  It is a bugfix release.

Changes from 20131015 to 20131027:
Related to the systmed-nspawn I/O bug workaround:
 * librechroot: It is now an error instead of a warning if stdin isn't
   a TTY
 * librechroot, libremakepkg: Now adds a bunch of extra
   carriage-returns to the output, to work around the systemd-nspawn
   bug.
Other changes:
 * librechroot: It now checks that the chroot directory isn't mounted
   with nosuid or noexec, which cause subtle errors.
 * librefetch: Cleans src-libre before running.  Not doing so may
   cause unreproducable builds.
 * pkgbuild-check-{nonfee,licenses} have been merged, and
   pkgbuild-summarize-nonfree has been added.  The new merged script
   fixes several bugs in the scripts, mostly related to split
   packages.
Bugfixes:
 * libremakepkg: [repo] is now configured to be highest priority, not
   lowest.
 * pkgbuild-check-nonfree: several fixes related to split packages.
 * librechroot: Fixed grammar in one of the error messages ("a"/"an").

Happy hacking,
