bugfix

[Juergen Reuter]

Hi, all!

Below, I have included three small patches against 1.3.86.  The first
and second one become relevant when Score.numberOfStaffLines is set to
an *even* number; they fix the y-coordinates of ledger lines and dots.
The third one becomes relevant for any Score.numberOfStaffLines other
than 5 and fixes the y-coordinates of breathing marks.

BTW., in my opinion, it would be nice to be able to control the
thickness of ledger lines with a property and/or make it dependent
from Staff.rulethickness.

Bye,
     Juergen

P.S.: I get thousands of "dvips: Couldn't find figure file src:xx:yy;
continuing" due to the src:special feature as introduced in 1.3.73.
Is there is possibility to turn off this feature?
