Added Google maps link to visiting addresses

Like the title says.

Decided to go for the minimal solution, which is q=lat,lon. 
I've tried putting in the postcode but unfortunately not all courts do have them. 
I've tried a compromise where I'd have ll=lat,lon&q=postcode or q=name, postcode but it was rather erratic for reasons beyond me. 

This will have to do. We can have another look after the data cleansing. 
Could the IF statement be this written as one line:
- track_js = "_gaq.push(['_trackEvent', 'court-detail-page', 'google-maps-clicked']);" if Rails.env.production?
