Easier Object Editing

[Richard Shann]

I've long meant to update the command

Command: Edit at Cursor
Edit in the context of the object at the cursor.
Location: Main Menu ▶ Edit
Internal Name: EditObject

which is the one run when you right click on any object in the Denemo
Display (aka Edit Window).

This period has given me the time to do that, and the result is now in
last night's build. By positioning the cursor on a note or chord or
other object you can re-run the command that created any specific
attribute attached to the object in edit mode (if it has one) or run
whatever other edit procedures are available. For example, a trill can
be edited to appear beneath instead of above a chord.
