Let the dump command copy a service.

If an optional second argument is given to dump, the name of the service
in the output will be set to the argument's value.  In any case, an
"install" line will be written, replacing the Application dump line.

Thus a service can be copied by running:

    nssm dump <servicename> <newservicename> | %COMSPEC% /k
