Method abridge

/**
 * Abridges text strings over the specified character limit. The
 * behavior will insert an ellipsis into the text replacing a section
 * of variable size to ensure the string does not exceed the defined
 * maximum length. This method is UTF-8 safe.
 *
 * For example, it transforms "Really long title" to "Really...title".
 *
 * Note that this method does not scan for HTML tags so will potentially break them.
 *
 * @param   string   $text    The text to abridge.
 * @param   integer  $length  The maximum length of the text (default is 50).
 * @param   integer  $intro   The maximum length of the intro text (default is 30).
 *
 * @return  string   The abridged text.
 *
 * @since   1.6
