Fileselector: add option that allows to select folders and files at the same time
Currently, the file selector (/static/js/vispa/file/fileselector/fileselector.js) can only add either files (folderMode = false) OR folder (folderMode = false). It would be great (absolutely necessary) to have an option that allows to select folders and files at the same time.
