[IZPACK-1149] - Allow ability to generate automatic installation file when shortcuts not selected in console mode

This is to address: http://jira.codehaus.org/browse/IZPACK-1149

Added missing logic to the ShortcutPanelConsoleHelper so that the ShortcutPanelLogic is informed that shortcuts should not be installed. This should fix the issue of the automatic installation file failing to generate.
