[Denemo-devel] Transpose

[Richard Shann]

I've done some work on this - setting the interval from selection makes
no sense if you are only getting a single note.
So I have added the equivalent for setting the interval c - (current
note) from the note at the cursor.
But internally the names and structure are not looking nice and there is
no warning that "f g" will not do except for Print transpositions.
