#16 Schedule duplicate batches

A feature request has come in at https://social.typica.us/@NorthRiver/100784300689449458 requesting the ability to enter batch data once and have an easy way to replicate that multiple times. I know that there are lots of roasting companies that run standardized batch sizes and a feature like this could streamline things for those companies so I'm not opposed to adding that, but I'm unsure what the best approach here is. In addition to creating the duplicate scheduled entries, it's also important that it's possible to easily print the unique batch tags for each scheduled batch.
