[PATCH] gitk: When a commit contains a note, mark it with a yellow box.

[Raphael Zimmerer <killekulla@rdrz.de>]

It is desirable to see at a glance which commits do contain notes.
Therefore mark them with a yellow rectangle.

That can be suppressed with `gitk --no-notes`.

Maybe this patch is helpful. Sorry for any tcl/tk nonsense, it's not
my first language...
