File close/save menu item

[GoogleCodeExporter]

Task:

A file->close menu option that is only enabled if something closeable is 
visible on the screen. It will then close that thing which will either be a 
maze in the maze editor or a script in the script editor.

The design proposal involved the primary frame registering a listener with 
the maze editor and script editor panels. The panels will then notify the 
primary frame when something is or is not on screen that can be closed and 
who should be notified when a close operation occurs.

This goes for the file->save operation as well.
