Adds support for windows with the use of AutoIt3

[MarcusNoordstrom]

The reason for using AutoIt3 is for smoothness, using pyautogui is very 'jittery' also trying to use Win32.dll for some reason makes it jitter, but using AutoIt3 makes it smooth.

See comments in line 196 inside Mouse.py for more information.

Line 196 in mouse.py

For Windows:    
Generates a file (mouse.au3) in ./tmp/ and runs it with AutoIt3

You need to put AutoIt3.exe in your environment paths, or you can replace 'autoit3',
in line 233 with the path to autoit3
