Make RAW_POST_DATA accessible

Feature added with changeset 409.

Three new methods were added to the stubRequest interface which allow acces to the raw data:

<?php
/**
 * checks whether raw data is valid or not
 *
 * @param   stubValidator  $validator  validator to use
 * @return  bool
 */
public function validateRawData(stubValidator $validator);

/**
 * returns the validated raw data
 * 
 * If the validator says the raw data is not valid the return value is null.
 *
 * @param   stubValidator  $validator  validator to use
 * @return  string
 */
public function getValidatedRawData(stubValidator $validator);

/**
 * returns the raw data filtered
 *
 * @param   stubFilter  $filter
 * @return  mixed
 * @throws  stubFilterException
 */
public function getFilteredRawData(stubFilter $filter);
?>

Request classes that extend the stubAbstractRequest class have to implement a new method:

<?php
/**
 * returns the raw data
 *
 * @return  string
 */
protected function getRawData()
?>

This method returns the raw data, in case of the stubWebRequest class this is the raw post data.
