Title: Piwik ecommerce tracking

Added ecommerce tracking calls for the open source analytics [Piwik](http://piwik.org/) after checkout.

This does not add any new admin options but instead works with the [WP-Piwik plugin](http://wordpress.org/extend/plugins/wp-piwik/) to find out whether to insert the javascript or not. If WP-Piwik is installed and set to insert page tracking code into every page, we insert the ecommerce code at the thankyou hook, too.

Tracking cart updates and product views is still a todo. See http://piwik.org/docs/ecommerce-analytics/ for possibilities.
