Subject: [PATCH] grabrfc: update fetching

The canonical server for fetching draft RFCs is defunct for ftp
access, so a mirror site is now used.  Add -d flag to fetch draft RFCs
but otherwise do not.  When fetching drafts, also fetch index and
abstract files.  For both normal and draft RFCs, only look for .txt
files as there a lot of other files in remote directories that are not
relevant.
