Invert the meaning of instrumentTransposition again.

The problem is that all of the available user-level documentation
(like with instrument definitions) does not really match the sign of
instrumentTransposition that has been chosen (and flipped back and
forth) in order to let the bug fixed with issue 754 result in audible
pitches that have some relation of not purely mathematical interest to
the input.  As this incentive is no longer present, it makes no sense
to maintain this incomprehensible sign convention.


This basically reverts commit 1965ca6b70aaf2c04a25ace9ed3f1fb4e1222f5a
and the preceding one.

Files affected:

Adapt input/regression/quote-transposition.ly to new realities

This currently includes the patches for issue 754 and will need to get
rebased once those make it to master.
