PhrasingSlurDashed

[Henrik Evers]

Hi,
I need PhrasingSlurDashed, as Tie and Slur affect the underlaying texts, and 
only PhrasingSlur does not. We have to sing some words on one single note and 
in other stanzas one word on one note, while the note itself stays the same. 
So I'd like to indicate with a "PhrasingSlurDashed" that the phrase is valid 
for a certain stanza, but not necessarily for all. 

Example:

Sopranos: e d c
Altos: a a a

Words stanza 1: I will be
Words stanza 2: to

So, Altos need dashed phrasing slurs to show some stanza needs holding here. 
While the text of stanza1 needs to be correctly distributed.

I hope this time it is ok to post in the devel-group. Last time I got my head 
washed because of an ordinary question. Sorry for that.

Regards,
Henrik

BTW, thanks for your great work!
