Error detect the location result from Yahoo

[bbiao]

The original codes in indicator-weather
if (yahoo_woeid_result['ResultSet']['Error'] != 0) and (yahoo_woeid_result['ResultSet']['Results'] != None):

Yahoo return yahoo_woeid_result['ResultSet']['Error'] as a string, so it will never be equal to 0. After apply the location it will crashes, and error messages are:
AttributeError in export_location_details(): Location instance has no attribute 'location_code' (as reported here: https://bugs.launchpad.net/ubuntu/+source/indicator-weather/+bug/821233)

above code should modify to

if (yahoo_woeid_result['ResultSet']['Error'] != '0') and (yahoo_woeid_result['ResultSet']['Results'] != None):

Platform: Ubuntu 12.10 + Unity
Version: 12.07.30 'Cloudy 10'
After the patch, it works fine for me
