- Upgraded to Norconex Importer from 1.0.0 to 1.0.2.
- Connection timeout now 30 seconds in DefaultHttpClientInitializer.
- When deleting downloaded files, the text file from the importer
  output is now also deleted as URLs are being processed, 
  greatly reducing the number of files on disk during the crawling
  process.
- The application now prints the full path of an error file when
  an error occurs on startup (error-*.log).
- Fixed java.io.NotSerializableException when cloning HttpCrawlerConfig
  (when &lt;crawlerDefaults&gt; is used).
