LilyPond 2.13.36 released

[Graham Percival]

We are happy to announce the release of LilyPond 2.13.36. This release
contains the usual number of bugfixes. However, a number of critical
issues still remain, so this release is intended for developers only.

Please note that this is *not* the third alpha test. Due to a number
of untested changes to our build process, we cannot be at all
confident about the quality of this release.

Cheers,
- Graham
