cura is just a front-end, and heavily depends on its dependencies.
without updating depended libraries, new version will not provide what
the release note says. this is especially true in this PR, as the reporter
needs fixes in cura engine, the slicer.

Submitter was not clear with the bugs present. In any case I have corrected
a few missing dependancies and am committing two of the dependencies
for cura-engine.
