    Check for NULL pointers before finding the syshandle · da9f2a03

    menu.c: if NULL return -1, this has the added advantage that a menu maker (see event_attachmenumaker) can return NULL to mean "no menu thanks" and not data abort in event.c
    dbox.c: if NULL return 0, this is somewhat consistent with template_syshandle()
    menu.h: typo in comment corrected
