New upstream release.

Biggest changes are:

• There is now a subpackage pungi-utils with some extra tools. The hook for sending notifications to fedmsg has been moved to this subpackage.
• The command line arguments for pungi-make-ostree have been changed a little.
• We now have support for handling non-blocking deliverables at per-arch granularity.
• Noarch debuginfo packages are now correctly included in the compose.
• Ostree installer images have a type in metadata listed as dvd-ostree to distinguish them from other images.
• It is now possible to add extra RPM repos when building the ostree installer.
• All temporary files are now placed into the work/ subdirectory to reduce chance of machine running out of disk space due to full /tmp.

And a lot of other small fixes.
