main_menu_config: New plugin to configur the main menu order

Browse source 
Plugins/Applications/main_menu_config allows you to edit the
main menu order without having to manually edit config.cfg.

Press the standard OK button to access the internal menu
which allows you to move items up/down in the order and toggle
their visibility. Exit via this menu to have the order saved.

(Suggestions welcome to improve this UI)
