Lance Stout 4375ac7d8b Underscore names by default.
Stanza objects now accept the use of underscored names.

The CamelCase versions are still available for backwards compatibility,
but are discouraged.

The property stanza.values now maps to the old getStanzaValues and
setStanzaValues, in addition to _set_stanza_values and
_get_stanza_values.
