Update Dramatis Personæ for Dramatist 2.0
Update `dramatist.cfg` for Dramatist 2.0

• Headings are now customized quite differently.
  I’m removing them entirely until I decide what I want.

• Dramatist now provides `\character` for where I’d used `\name`,
  but with a deeper hook into the package’s internals.
  Uses of `\name` will have to be rewritten, not just replaced.

• Along those lines, `\And` has been temporarily removed.
  I’m replacing it with `\&` in the text: I’ll need to come back to this.

• Continuing dialog after a bit of `\direction` now works out-of-the-box,
  but produces normal paragraph indentation.
  I still need `\speakercontinues`, but its definition is much simpler.
