[PATCH] Quoting different types of events for \cueDuring and \quoteDuring

[Reinhold Kainhofer]

Typically, \quoteDuring is used to duplicate everything in a voice,
while \cueDuring is used to only quote the notes, but not e.g.
phrasing, slurs, accents, markup, etc.
    
So, this patch adds an additional property quotedCueEventTypes in
addition to quotedEventTypes, which allows to quote different types
for \cueDuring than for \quoteDuring.
    
By default, \quoteDuring now quotes everything (i.e. StreamEvent), while
\cueDuring quotes only notes, rest, ties, beams and tuplets.

Here's the patch (also includes a regtest):

Okay to apply?

Cheers,
Reinhold
