Editing Aligning and centering instrument names

The horizontal alignment of instrument names is tweaked by changing the <code>Staff.InstrumentName.self-alignment-X</code> property. The <code>\layout</code> variables <code>indent</code> and <code>short-indent</code> define the space in which the instrument names are aligned before the first and the following systems, respectively.
