-- Bugfix #3458: keyblock.getData() was getting vertex data from keys
incorrectly, including wrapping curve data as BezTriples. Needed to
make a change to beztriple module so we could more easily create a
"thick" BezTriple object similar to Blender.BezTriple.New().

The change to BezTriple.h pointed out some dead code in the Ipocurve
module that could be removed.
