"Fake Deeply": adjust transphobia strategy

The slur usage had me feeling shy about publishing. Coach thought it
was inconsistent with the pronouns. (A viewpoint character that uses
the slur, should also misgender.) Demoting the slur (to just "trans")
and inserting one quieted scare
(http://zackmdavis.net/blog/2012/10/the-quieted-scare-convention/)
makes the characterization more consistent and will probably land
better.
