Ability to submit multiple files at once

[Lars-Codes]

Right now, the user can only submit 1 file at a time.

Would be cool if the user can select multiple files and queue them up to 1 printer.

This software right now supports auto-queuing and load balancing. Meaning, if you queue up 1 file and make a quantity of 500, and select 3 different printers, that load will be evenly distributed across all 3 printers.

There are a couple ways we can think about this.

Maybe if the user selects multiple files, they can only select 1 printer. Or, maybe there could be 2 different "modes" or tabs you can click -- single-file mode or multi-file mode on Submit Job. Perhaps on multi-file mode, the user can choose quantity/printer for each file and it wouldn't include the same load-balancing feature. Idk. Something to think about. This would be a cool feature because sometimes students submit 10 files to the lab and we want to queue all 10 files to 1 printer. Think about what would make the most sense to implement from a user standpoint.
