Update to 0.7.1:

This is a maintenance release. It primarily includes bug fixes and
build fixes since the 0.7.0 release with no new features. That
said, the most notable aspect of this release is that it is buildable
with the version 0.9.0 of the Ixion library which was just released
a week ago. So, if you are trying to package and distribute the
newly-released Ixion library but are unable to do so because of
Orcus not being buildable with it, you might be interested in this
release.
