Summary: Remove unncessary NLST from ftp transfers

Initial Comment:
Using urllib (or urllib2) to open FTP URLs will attempt
a 'nlst' (directory listing) before retrieving the
file. Some FTP servers block directory listings, but
allow 'getting' files just fine.

Having urllib do a NLST before retriving files is
totally unnecessary, and will fail given the FTP server
mentioned above. If a file is not 'gettable', which is
what the probable intention of NLST is, it will fail in
the retrieve process.

This patch removes the NLST from urllib. As a bonus,
this makes FTP transfers faster.
