Add feature to rearrange cluster bundle / unbundle terminals

[Robzilla]

Proposing adding right-click menu option for bundle and unbundle cluster elements, which allows the user to rearrange the order of elements with wiring automatically updated.  This is a frequent and tedious task when cleaning block diagrams that currently involves many steps and introduces risk of mis-wiring - this change would leverage existing behaviors to reduce time spent cleaning block diagrams.

This would be nice to have on math and logic primitives too!
