Add "minimum strut length" and "match strut length to longest trapeze on run" options in the Hanger

When it comes to Pre-Fab, cutting one length of strut for an entire run is more efficient. Also, instead of sorting through pallets of different pre-cut strut lengths to find the one piece you need, one-size-fits-all works best for those long runs of conduit. Allow options in the Hanger Placement Settings Menu to match all strut lengths and set a minimum strut length for that run, in addition to the Auto-Detect feature for strut length already in use.
