Detect if aliases are involved in a PUT and support specifying COPYGRP or COPYGROUP; support GENS=

[catherdersoftware]

Implement the following behavioral changes:

• If aliases are selected and base member is selected, use COPYGRP (any PDSE involved) or COPYGROUP (no PDSEs involved)
• If aliases are found for the selected member but not selected, prompt for copying of aliases
• If aliases are selected but base member is not selected, prompt for verification that the alias is to be copied without the base member
• Prompt for GENS= (GET & PUT)
