LilyPond 2.17.29 release

[Phil Holmes]

We are happy to announce the release of LilyPond 2.17.29, which will
be available within a few hours of this announcement. This release
contains the usual number of bugfixes and enhancements, and contains some
work in progress. You will have access to the very latest features, but some
may be incomplete, and you may encounter bugs and crashes. If you require a
stable version of Lilypond, we recommend using the 2.16 version.
