Split out the media/dists directory to avoid inode overload

[eeaston]

Unix directories really don't like having thousands of files in them, especially if they're hosted on NFS. You end up not being able to look at them as your shell hangs trying to get all the inode metadata. Storing all the distributions under media/dists will eventually cause this problem when your database gets big enough. What do you think of using the first letter of the package name to split it out? Eg:

dists/a/argparse-1.0.tar.gz
dists/r/requests-1.3.tar.gz

Sounds the right thing to do, removing "Suggestion" from the title :)
