modified: ../app/src/processing/app/Editor.java

Changed Editor.java to add optional rescan of serial ports.
Original behavior of Tools menu would rescan serial ports every time it is
opened.  This can be time consuming when you have an abundance of virtual
or bluetooth serial devices.  New behavior adds a check button to serialMenu
to disable the automatic scanning and a button to manually scan ports.
