This version of the Statcounter module no longer uses the block system to insert Statcounter code on drupal pages. It also introduces the following new features:
    * Selectively track/exclude certain users, roles and pages
    * Cache the Statcounter code on your local server for improved page loading times
    * Access denied (403) and Page not found (404) tracking
    * DoNotTrack support (non-cached content only)

#273190: add README file that explains how to use the block system to specify a more detailed page visiblity.
