Add a new field to a section of a settings page

Part of the Settings API. Use this to define a settings field that will show as part of a settings section inside a settings page. The fields are shown using do_settings_fields() in do_settings-sections()

The $callback argument should be the name of a function that echoes out the html input tags for this setting field. Use get_option() to retrieve existing values to show.
