 * \author  Viljami Korhonen, mindflayer@allacrost.org
 * \brief   Header file for the boot-mode menu
 *
 * This code extends some parts of the OptionBox to match the
 * requirements of the boot menu. This includes features like multi-depth 
 * menus and custom visualization as well as custom event handling.
 * However, no inheritance was used as I found it to be more of a nuisance
 * than benefit in here!
