(change): don't autocorrect search input

- at least in my experience, I'm typing lots of japanese words, so
  the autocorrect gets in the way a lot
  - while it may be useful for some english words, I think the
    frustrating and annoying experience it gives for japanese words
    far outweighs the usefulness such that it should be disabled

- changing autocorrect to false also turns off the spellcheck, so
  no more red lines appearing in the input either
