Option dice now have their own database table

This is a refactoring of 90_mood_swing that should leave functionality unchanged, but allow me to better support remembering option values chosen in previous rounds.

This pull request depends on pull request #774 (mood swing).

Requires database update option_SQL_table.sql.
