Isolated durations in music sequences now stand for unpitched notes

This allows for things like

\new RhythmicStaff { 4 4. 8 4 | 4 \tuplet 3/2 { 2 4 } 4 }

"unpitched" simply means that this is rendered as a normal  
NoteEvent,
but the pitch information is missing and has to be filled in by some
other means (RhythmicStaff is an exception since it ignores specified
pitches anyway).


Also contains commits:

Regtest for rhythmic sequences.



Interpret #{ -3 #} as postevent rather than negative number

Since #{ 4 #} is interpreted as duration rather than number, interpreting
negative integers as numbers rather than fingering is not really helpful.



Let #{ 4 #} be a duration while #{ 4 \cm #} stays a length

An UNSIGNED not followed by a NUMERIC_IDENTIFIER inside of #{ ... #}
is interpreted as a duration rather than a number.  Also, inside
of #{ ... #} no "numeric expressions" using binary operators +-*/  
are
interpreted.

The behavior of (signed and unsigned) integers and numeric expressions
in assignments and as function arguments rather than inside
of #{ ... #} is not affected.
