Extract wind and humidity values

[GoogleCodeExporter]

Extract wind speed and humidity values from the strings, provided by Google.
It's required to:
- display the values in the correct unit (issue 14)
- calculate wind chill and humidex (issue 16)

• Blocking: Incorrect units #14, Temperature with wind chill or humidex #16, Incorrect units #14

The problem:
Google Weather API doesn't provide the numeric wind and humidity values. All 
that we have is the following:
<humidity data="Humidity: 48%"/>
<wind_condition data="Wind: NE at 9 mph"/>
The text differs for different languages. We need to parse it to numeric values.

Workflow:
- Add methods to interface: 
http://code.google.com/p/weather-notification-android/source/browse/src/ru/gelin
/android/weather/WeatherCondition.java - to get wind speed and direction, and 
humidity value. The backward compatibility with existed clients shouldn't be 
broken. The wind speed should be returned in three units: mph, km/h, m/s.
- Add implementation to 
http://code.google.com/p/weather-notification-android/source/browse/src/ru/gelin
/android/weather/google/GoogleWeather.java. Need to ask weather for English and 
system locale (better to use single HTTP connection for both).
- Add unit tests to: 
http://code.google.com/p/weather-notification-android/source/browse/test/ru/geli
n/android/weather/google/GoogleWeatherTest.java - to be sure that everything 
works.

You can download weather information in all available languages by running this 
script: 
http://code.google.com/p/weather-notification-android/source/browse/misc/fetch_s
amples.py. And see all the wind and humidity values by running this: 
http://code.google.com/p/weather-notification-android/source/browse/misc/analyze
_samples.py

Wojciech Zygmunt Porczyk:

there is simple method to get SI unit (km/h): just add &hl=en-gb to
google api query:

http://www.google.com/ig/api?weather=warsaw&hl=en-gb
http://www.google.com/ig/api?weather=warsaw&hl=en

Aallows to display more correct values because of avoiding of conversion
