Drum patch

[Rune Zedeler]

1.3.142.rz1
===========

* Added "hacky" drum notation/midi. See input/tricks/drums.ly and
  ly/drumpitch.ly. Moved midi-instruments to scm.

* Added temporary nested staffgroups/choirstaffs support
  use Context InnerStaffGroup / InnerChoirStaff.


Sorry for loads and loads of minor stupid changes (respacings,
tab->spaces, etc) - but for a while I have had to update by patch and
therefore theese minor differences.
