[PATCH] Menu: add box stype entry

[Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>]

this will allow you to create a box style entry

via C API by specifying the type as

struct menu_entry me = {
	.display "test",
	.box_state = MENU_ENTRY_BOX,
	.box_action = action_to_run,
}

and via shell
menu -e -a -m <menu> -c <command> [-R] [-b 0|1 -B <select action>] -d <description>
menu -e -a -m <menu> -u submenu -d [-b 0|1 -B <select action>] <description>

-b with 0 for not selected and 1 for selected
and -B for the command to run when changing state
