new lilypond-auto mailing list for google code issues

[Graham Percival]

We have a new mailing list for automatic messages.  All updates to
google code issues are now sent there instead of bug-lilypond.
The reply-to headers for -auto are set to -devel.

https://lists.gnu.org/mailman/listinfo/lilypond-auto

Note that you can get direct emails for issues by "starring" the
issue.  In addition to being sent to your google account directly,
those emails also allow you to add comments to the issue by
replying to the email.
