Compressing ELPA (was: GnuTLS/TLS proposals for after the release)

Along the same lines, it'd be good to require the presence of
a decompressor, so that we can start compressing the ELPA archives.
Distributing files as .el or .tar is a waste of disk space and
network bandwidth.

I know in theory we could have the web server de-compress the files on
the fly if/when the client doesn't support compression, but somehow
I wasn't able to make this work
