Directed \tweak commands in 2.15.39

[David Kastrup]

Hi,

with regard to the latest development release (and 7th stable release
candidate), I wanted to point out a new feature that came in as a
side-effect of reimplementing footnotes, an optional layout-object
argument for tweaks:

<URL:http://lilypond.org/doc/v2.15/Documentation/notation/the-tweak-command>

Footnotes have gotten a new interface.  The documentation for this
<URL:http://lilypond.org/doc/v2.15/Documentation/notation/creating-footnotes>,
while reasonably complete and correct, is currently being rewritten in
order to better match LilyPond's standards.
