Support HttpGet command

Browse Source 
HttpGet command send a HTTP Get request to specified URL and return the response from website or error message if failed.
Note: This command support URL encoding, so you do not have to do encode by yourself. For example replacing all " " with %20 is no necessary.
Format:
httpget <url>
With HttpGet command you can do a lot of things.
For example:
- Retrieve your physical location:
httpget http://ipinfo.io/geo
Result is a JSON object
{
  "ip": "8.8.8.8",
  "city": "Mountain View",
  "region": "California",
  "country": "US",
  "loc": "37.3860,-122.0840",
  "postal": "94035",
  "phone": "650"
}
- Control another Sonoff switch directly:
httpget http://192.168.1.130/cm?cmnd=power off
