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.
