G.K.MacGregor 74ebc91ee6 Split Insert triplet button, and add mode menus 
The "insert before" and "insert after" buttons will drop a menu to
select the new triplet mode, allowing triplets with different modes to
be inserted with one less mouse click.

The "insert copy" button still does the old behaviour of inserting a
copy of the currently selected triplet.
