[9front] [PATCH] grabrfc: update fetching

[Romano <unobe@cpan.org>]

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.
