Refs #17538. Adds ability for user to paste a custom BED region into the multi-region dialog box instead of having to provide a URL to an on-line server.  It still supports the URL through UDC however, which is more efficient for large custom region lists and also provides backwards compatibility.  Uses sha1 instead of md5 for faster speed now.
