Intensive commands are processed on the client only, as opposed to
twice. an array of objects, their corresponding UID and ID are sent to
the server. Sending the objects as an array, despite the size the array
can reach, should be better than the way this was set up before.
Needs testing on a full server however.
CursorTarget should always be passed from fn_selfActions, not reacquired
in action scripts. This is to ensure the same object is referenced. Plot
Management maintain_area is called from the dialog button, not
fn_selfactions.
