Edit true position FCF (F9), change secondary datum C to MMC, press OK, PC-DMIS crashes

<< Don Turcotte  --  03/18/09  09:44:43>>
Edit true position FCF (F9), change secondary datum C to MMC, press OK, PC-DMIS crashes.   This is a problem in both V432 and V44B.

Steps to reproduce:
Load program attached to 246135
F9 on FCFL&Auml;GE2
Change secondary datum C to select MMC (but leave modifier list open)
Click OK

If you select MMC, then click elsewhere on dialog to before clicking Ok, this does not crash

Results:
PC-DMIS crashes
<<END>>

The original fix here was causing a crash in V432 for the program in #248043.  I have reworked the fix to solve this PR and leave #248043 working correctly.

CPCDtp_start_location::duplicate_datums() must delete the drf alignments since they will reference any previously duplicated datums.
Fixed in V432, V44B.
