Make jumping spiders jump instead of blink

- Because they blinked they could go through grates
  (Mantis #5590) which didn't make sense for physical movement

- Verb was wrong and purple clouds appeared despite some special-
  casing to prevent this; because crawl_state.which_mon_acting()
  actually returns an inaccurately null value during monster
  spellcasting and some other contexts. That function is only designed
  for use in handling "comes into view" messages properly and needs
  fixing to be fit for any general purpose.

- "Appears out of nowhere" message was inaccurate, this would
  only have been seen rarely, but "leaps into view" is better
