Force all chord symbols to a chosen staff

Background: A user requested, among other things, the ability to have all chord symbols on the same staff. This MU3.6 plugin does that. It may, or may not, run on MU4 (it has SmartQuit & Component.onCompleted).

The default targetStaff is 1, the first track. Change the number of var targetStaff, right after the onRun statement.

To test: select measure 1-4 in test.mscz & run the plugin. You should get identity of measure 1-4 and measure 5-8
