Adaptive re-fetch interval. Detecting umodified content
-------------------------------------------------------

         Key: NUTCH-61
         URL: http://issues.apache.org/jira/browse/NUTCH-61
     Project: Nutch
        Type: New Feature
  Components: fetcher  
    Reporter: Andrzej Bialecki 
 Assigned to: Andrzej Bialecki  


Currently Nutch doesn't adjust automatically its re-fetch period, no matter if individual
pages change seldom or frequently. The goal of these changes is to extend the current codebase
to support various possible adjustments to re-fetch times and intervals, and specifically
a re-fetch schedule which tries to adapt the period between consecutive fetches to the period
of content changes.

Also, these patches implement checking if the content has changed since last fetching; protocol
plugins are also changed to make use of this information, so that if content is unmodified
it doesn't have to be fetched and processed.
