Export Multiple PDFs with nice renaming in to a single directory

Old version of Readcube allowed you to highlight multiple articles and export the PDFs into a new directory as a copy while keeping them in your file system/libary. Useful when wanting to share a few papers but not a whole library. This allows you to take advantage of the "neatened-up" PDF renaming convention when you import a PDF. I miss this feature in Papers 4!
