lily 1.5.53

Hi y'all,

.53 is out there.  Attractions in this release: completely revamped
accidental placement.  This should fix the embarassing mistakes that
lily does when you typeset accidentals close to the octave boundary
(i.e. <bes4 cis> ).  On the negative side, I have probably broken all
sorts of subtleties of the new accidental creation of Rune's.  I don't
feel like looking into them now, but if you simply report the new
problems, it could increase the chance of them being fixed :).

Second, the hallmark of Your Average LilyPond score has been
changed. For a long time I loved the layout of the G clef, and I could
use it to spot lily output from a distance. Yet, there were some
faults with it. The most important fault was the downstroke, that was
a straight line segment.  .53 contains a somewhat more curved G-clef
that took a long night of sweating on MF code. I hope you like it.

Other attractions: a new dynamic z, emacs mode updates by Heikki,
raggedright code by Juergen, various bugfixes
