Changes the item for a given window in the Window menu to a given string.
Original signature is '- (void)changeWindowsItem:(NSWindow *)aWindow title:(NSString *)aString filename:(BOOL)isFilename'
Available in Mac OS X v10.0 and later.


- aWindow (NSWindow)
- The window whose title you want to change in the Window menu. If aWindow is not in the Window menu, this method adds it.
- aString (NSString)
- The string to display for the window’s menu item. How the string is interpreted is dependent on the value in the isFilename parameter.
- isFilename (Boolean)
- If NO, aString appears literally in the menu; otherwise, aString is assumed to be a converted pathname with the name of the file preceding the path (the way the NSWindow method setTitleWithRepresentedFilename: shows a title)

- Available in Monobjc Bridge: 10.6 (For Mac OS X 10.6 and later), 10.5 (For Mac OS X 10.5 and later)
