Description:
Fix issue 75: Allow multiple concurrent slurs

Rewrite the Slur_engraver and the Phrasing_slur_engraver to support
multiple concurrent slurs. The default lilypond syntax using parentheses
still supports only one slur at a time, but by adding a slur-id property
to the (Phrasing)SlurEvent music expression, one can create multiple
concurrent slurs, each with a different slur-id.

This finally allows appoggiaturas and acciaccaturas (which both create a
slur from the grace note the the next note) to be placed inside a slur.
