 - added a label in the status bar to show if the workplace is active and what size it is
 - now the Edit command (either from Menu Edit ->Edit Object) or through the shortcut key (E key) or project tab context menu works also for the CNCJob objects (will open a text Editor with the GCode)
 - fixed the object collection methods that return a list of objects or names of objects such that they have a parameter now to allow adding to those lists (or not) for the objects of type Script or Document. Thus fixing some of the Tcl commands such Set Origin
+- reverted the previous changes to object collection; it is better to create empty methods in FlatCAMScript and FlatCAMDocument objects
