; Function: IPv4 ping with name resolution, based upon 'SimplePing' by Uberi ->
; http://www.autohotkey.com/board/topic/87742-simpleping-successor-of-ping/
; Parameters: Addr - IPv4 address or host / domain name.
; ---------- Optional:
; Result - Object to receive the result in three keys:
; - InAddr - Original value passed in parameter Addr.
; - IPAddr - The replying IPv4 address.
; - RTTime - The round trip time, in milliseconds.
; Timeout - The time, in milliseconds, to wait for replies.
; Return values: On success: The round trip time, in milliseconds.
; On failure: "", ErrorLevel contains additional informations.
; Tested with: AHK 1.1.22.03
; Tested on: Win 8.1 x64
; Authors: Uberi / just me
; Change log: 1.0.01.00/2015-07-16/just me - fixed bug on Win 8
