RSSes for NEW available on ftp-master

The two RSS feeds previously at http://people.debian.org/~filippo/NEW_rss/ have been moved to a more proper location on ftp-master and the script (tools/queue_rss.py) merged into dak thanks to ganneff.

JFTR the script scans a directory with .changes files (which happens to be NEW in this case) and generates the said feeds, it is not tied to ftp-master and requires python-pyrss2gen and python-debian.
