Overwrite Option on MoveWave

As subject line says.

Would having a /Kill flag for duplicate make that function as (or more) useful than this change? This flag could work as proposed below. This seems broadly useful to me.


/Kill = 0: do not kill source wave (default)

/Kill or /Kill = 1: kill source wave of duplicate was successful (i.e., duplicate might fail without /O flag if the destination wave already exists)

/Kill = 2: kill source wave regardless of whether duplicate is successful

In which situation would you use `/Kill=2`? And moving the wave should also be faster as it does not duplicate the contents.
