Fix duplicate execution during bulk input on delegated command (#133)

Commands that delegate to other commands were passing the bulk
input flag through to the subcommand.  Since the command being
delegated to is executed in a way that includes re-initialization,
this would re-run the entire bulk input again for each entry in
the bulk input file.  To fix this, that flag is now filtered out
when running each command for the bulk input file, to ensure that
no such recursion is possible.
