foreach-bug fixed
When there are no pins added to the usermap, the you got an invallid argument error, which is fixed now.
Sensor option added
Using GMA v3, it's mandatory to set the sensor paramater, so we did. This is a quote I found on stackoverflow:
"The sensor parameter doesn't give you any geo location capabilities it just lets us know as part of our licensing terms with our data providers that the map is being used in conjunction with some sort of geo location functionality."
