First implementation of infix mode

Three mode menu items appear in "Targets for Key Binding"
in the setup dialog and can be bound to a key.

"Move Interactive" will immediately start moving the
selection.

"Paste Interactive" and "Duplicate Interactive" will
paste and then immediately start moving.

Remaining issue: when Paste or Duplicate moves are
cancelled the pasted objects will still be there and
at the original location. So they are may be hard to
see. Also with Undo, two undo items are there: Paste
and Move.
