More locations for the weather plugin?

I don't know all codes and as I see the find option don't show all locations. But you can open the website weather.com and search there your location. For example if you search the "Milan" you'll get some links:

Code:

http://www.weather.com/weather/today/Milan+Italy+ITXX0042
http://www.weather.com/outlook/travel/businesstraveler/airportprofile/MXP:9
http://www.weather.com/outlook/recreation/golf/weather/weekend/?clubId=1036713
http://www.weather.com/weather/today/Milan+Hill+State+Park+NH+NHSPMH:13

Generally the last symbols are the location id: ITXX0042, MXP:9, NHSPMH:13
With the golf club the location id 1036713 don't works. But on that page we can find the links to the 10 days weather and other with the location id 1036713:5 and this works well.
