ubuntu-helpers: New script "enable-debsrc"

[Bryce Harrington]

I've added a simple little script to enable deb-src lines in
sources.list to ubuntu-helpers:

  https://git.launchpad.net/~ubuntu-server/ubuntu-helpers/tree/bryce/enable-debsrc

    This script modifies your /etc/apt/sources.list and
    /etc/apt/sources.list.d/* files, and for each enabled deb line, it
    uncomments the corresponding deb-src line.

In case anyone else finds it useful, there it is.
