Simplified code to return content enumerator
Changed page fetch actor to handle binary files and bring file encodings/miime types forward.  Temporarily removed document normalization at fetch time in favor of link normalization as it is only necessary for recursion at crawl time.  Document normalization will occur at display time on the fly.  This still must be implemented.
