GSM library webClient example needs fix

[dcuartielles]

This library has given us some trouble when trying it out at a course in Sweden. The request to the server is not including the HOST and some servers tend to answer with a 404 error. It should be corrected to:

// Make a HTTP request:
client.print("GET ");
client.print(path);
client.println(" HTTP/1.0");
client.println();
client.print("HOST: ");
client.println(server);
client.println();

Where the last three lines are missing in the current example.

well, seems a good pratice specially if the server is on a virtual machine I guess
