http://bugs.debian.org/658075
* debian/: Cycles support added (Closes: #658075)
  For now, this top feature has been enabled only
  on [any-amd64 any-i386] architectures because
  of OpenImageIO failing on all others
* debian/: scripts installation path changed
  from /usr/lib to /usr/share:
  + debian/patches/: patchset re-worked for path changing
  + debian/control: "Breaks" field added on yafaray-exporter
