Add native support of pitched ornamentations

[Xavier Scheuer]

Hi,

In some part of the thread "A must-see for anybody on this list" on
lilypond-user, Joseph Rushton Wakeling and David Kastrup agreed that
LilyPond is missing a proper command for pitched ornamentations.

Instead of the current code
  a4\mordent^\markup{ \flat }
we should have a dedicated command
  a4\pitchedMordent { bes }
that would properly change the accidental when transposed, like
\pitchedTrill actually works (IIUC).

This enhancement could be applied to all the ornament scripts, but
differently for each of them (turn for example could have the upper
note or the lower note (or both) with accidentals, so printed above
and/or below the turn).
