[Denemo-devel] Tweaking positions.

[Richard Shann]

I've now sweetened the interface to the tweaking of the positions of
items in the LilyPond output. Now you can start by hitting Edit
Directive & you get to drag in the print preview window & when finished
the tweak is applied (unless you cancel). You can still drag first and
hit Edit Directive after if you want.

The position tweaking scripts are (so far) for the D.Calfine and the
guitar finger/string number directives.
