tsc_SubMenuItem

This control is for use with the tsc_WizardMenu class.  Add it to the controls list to have it place a button with the specified text on the page.

When pressed this control will chain the submenu on to the wizard and present it as the next page.  The supplied tsc_WizardMenu should be an instance with a lifetime beyond that of the ShowDialog duration.  This behaviour is supported by the base class and no overriding is neccessary.
