Completely wire vocab words in YAML to the code.

This massive patch:
* Finishes working all the vocab words into YAML structures.
* Adds vocab ID generator functions.
* Redoes the input-getting system, removing the need for GETIN(),
  GETTXT(), etc.
* Changes advent<->ascii mapping to avoid the special 'shift'
  character.
* Works around some bad behavior in the dragon attack logic.
* Handles the reservoir magic word without changing the database
  contents.
