Would be nice to be able to add files in batches to comprehensive upload

Right now, when you upload, sometimes you have to carefully select particular files in the file browser, then drag them on to the dropzone:

Sometimes people want to add one batch of files, then a different batch of files, all for the same dataset. For instance, red_001-red_010, then also green_001-green_010. One option could be to allow dropping multiple files onto the dropzone and have a "proceed" button. The other option, which I think I like more, is to add a "add more files" button to the next screen that allows you to add more files to the dataset.

After discussion : a button to add more files would be enough

Yes, on this screen, just add a button to bring up a file browser to allow additional files to be added. Hopefully then we don't need to manipulate any girder components, etc.
