Minor menu reorganization: Determined how to place plugins in a desired menu folder.  Setup permissions in BasicApp and VisatApp accordingly to override these methods with SeadasApp.  Put Bathymetry and Coastline plugins into a "Masks" folder.  This revision also enabled removal a few separator lines in the Edit menu.  Added "OC" to a couple components in the OCProc menu to more clearly differentiate it from Processing.
