Romka's sandbox: Piwik Stats

This module is a backport to Drupal 6 of the module http://drupal.org/project/piwik_stats.

Differencies between this version of module and D7 version:

• working only with nodes,
• has several new widget settings:
  • XML-file cache lifetime (in D7 version this parameter set in code to value 24 hours),
  • Minimum value for one of the parameters (hits, visits, etc). Piwik won't return data for URL if it has views/visits/etc less then set here (Piwik API filters filter_excludelowpop and filter_excludelowpop_value),
  • Statistics for how much nodes have to be updated,
• in D7 version allowed only response from Piwik with code 200, in this version also allowed code 301,
• added messages about last statistics update and Piwik queue size on Status report page.

This module working in test-mode on two my sites, but it might have errors...
