Retagging Joyce’s dialogue

This is a to-do issue to pick out the various tasks discussed in #9:

• Convert all double-hyphen dialogue dashes to the quotation dash or horizontal bar.

• Shift the </said> tags in <said>―</said> structures to the end of character speech. Add all intermedial <said> tagging.

• Proof the </said> tagging for every episode. How? We will visualize all of the episodes in a browser and colour just the </said> tagged dialogue.
  Episodes remaining: 1. “Telemachus” 2. “Nestor” 3. “Proteus” 4. “Calypso” 5. “Lotus Eaters” 6. “Hades” 7. “Aeolus” 8. “Lestrygonians” 9. “Scylla and Charybdis” 10. “Wandering Rocks” 11. “Sirens” 12. “Cyclops” 13. “Nausicaa” 14. “Oxen of the Sun” 15. “Circe” 16. “Eumaeus” 17. “Ithaca” 18. “Penelope”

• Disambiguate the appropriate <emph> to <said> tagging.
  [there might be a few other stragglers]

• Add @who attribution for every instance of <said> (or in “Circe” <sp>). Use character names for the values.

• Switch @who values to @xml:id.

• Compile a <listPerson> dossier of speakers.
