Simple implementation of the Gemius Audience tracking script.
Updated tracking script to the new improved version that uses BrowserID based on a combination of 3rd party cookies, 1st party cookies and localStorage identifiers.
Tested up to WordPress: 3.5.1
The scripts are now implemented with wp_enqueue_script and wp_localize_script instead of simply including them in the footer.
Tested up to WordPress: 3.4.1
