Update relationship handler to no longer use depreciated api

This patch moves over the 'options' function to the 'option_definition' function. This allows for Views 3 to export things with nodequeue properly and 'options' is a depreciated.

 /**
   * Set default options on this object. Called by the constructor in a
   * complex chain to deal with backward compatibility.
   */
  function options() { }

This patch works in both Views2 and Views3 and behaves exactly the same as it use to.
