httpGET() sends wrong header info

[GoogleCodeExporter]

Currently only some GET requests succeed because the GET request is not 
properly formulated. Each line shall be terminated by a carriage return 
followed by a line feed.

Currently implemented:
  gsm.SimpleWrite("GET ");
  gsm.SimpleWrite(path);
  gsm.SimpleWrite(" HTTP/1.0\nHost: ");
  gsm.SimpleWrite(server);
  gsm.SimpleWrite("\n");
  gsm.SimpleWrite("User-Agent: Arduino");
  gsm.SimpleWrite("\n\n");
  gsm.SimpleWrite(end_c);

Should be:
  gsm.SimpleWrite("GET ");
  gsm.SimpleWrite(path);
  gsm.SimpleWrite(" HTTP/1.0\r\nHost: ");
  gsm.SimpleWrite(server);
  gsm.SimpleWrite("\r\n");
  gsm.SimpleWrite("User-Agent: Arduino");
  gsm.SimpleWrite("\r\n\r\n");
  gsm.SimpleWrite(end_c);
