Bendy octahedral. B-Bone with direction visual clue.

My gripe with bendy bone is that user have to choose to see either

a. bone segment, curvature, and twist using B-Bone
or
b. bone head/tail direction using Octahedral

there is no way to see both at the same time. I propose hybrid mode, B-Hedral (temporary name) This can also expand to hybrid stick as well.

Alternative solution is to only change b-bone to usual segmented blocks while show non-b-bone as octahedral.
