Properly handle Site Search

piwik_analytics should properly handle Site Search and not call trackPageView() when trackSiteSearch() is called.

I had the same Idea, but now I think maybe there is a way including the <%= piwik_tracking_tag %> but configure it to NOT track the actual site, so maybe I could put another <%= track_now %> tag somewhere - or just doing it with the javascript itself, so <%= piwik_tracking_tag %> would only prepare the javascript 'piwikTracker' for me, which I can use wherever I want. :)
