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.
