incorrect vertical spacing in pianostaff

[Marten Visser]

> I'm not top posting.

Pertains at least to 2.13.32 and up. Lower versions not tested.

between-staff-spacing #'padding should be relative to the actual 
staff size, but it's relative to default staff size.

Output for 2.13.35 is attached.

---------------------------------------
%{
Example:
 spacing between staves of pianoStaff does not scale with staff size
 Goes wrong in version 2.13.35, but also in 2.13.32. (No other 
versions tested.)
