As long discussed, many folks would benefit from being able to upload multiple files at once, such as when uploading a bunch of photos from an event.
We need the backend infrastructure for accepting multiple files in one submission, and some front-end UI for sensibly handling the name/description/licensing info for each file.
Separate bugs will cover specific UI implementations for the actual file selection, which is another fun thing. :)
