Fixes #8888

The Preferences dialog was not closing when the CLOSE DIALOG key binding was pressed. This was because when the user changed the tab, they needed to click the Preference Tab List. This ListView was not respecting the event handlers that were present on the dialog. To resolve this, an 'onKeyReleased' event was added to the ListView. The Preferences tab now closes when the CLOSE DIALOG key binding is pressed.
