Dead links for CDs/DVDs

[Jimmy Johnson <jimmy.l.johnson@gmail.com>]

Just a heads up guys,

The links for downloads have a typo which causes a 404.

For example, http://cdimage.debian.org/debian-cd/7.4.0/i386/bt-cd/ does not work. It has the wrong version number :(

These links should reflect version 7.3.0.

Cheers,

Jimmy
