Allow specification of multiple -id options on copy and prune commands.
Currently, these commands can operate either on all snapshot ids or just one, so if one has several snapshot ids in a storage, copying or pruning only some of them requires configuring/running several duplicacy jobs, one per snapshot id. For example, I have 12 snapshot ids, 10 backed up daily and 2 manually/irregularly, all pruned weekly using 3 different retention policies, and 9 of which are copied to cloud storage. The Web UI backup schedule requires 10 backup jobs, 9 copy jobs, and 2 check jobs. The weekly backup-and-prune schedule requires all jobs in the backup schedule plus 21 prune jobs.
