I was thinking we should serialize ALL options (so we can store
booleans) and stop relying on get_* functions to tell us that an
option doesn't exist. It would be a cinch to write a function
option_exists() and start serializing all options.

This would also reduce some of the confusion that develops when
escaping/unescaping strings for the database.
