new action tag: [clear_menu_item]

Browse Source 
Removes a menu item from the right click menu, the according event
handler if it had a [command] tag, and from being saved in the savefile.
Does not touch manually added events of type "menu item x".
Menu items were automatically carried over between scenarios so far,
causing potential savefile bloat by accumulating over the course
of a campaign.
