MAC OS support

[AXeL-dev]

This is a reminder for MAC OS support lack. To help you'll find below a list of things that may need or not to be changed.

Things already supported on MAC:

• pyautogui, but still need to be fully tested
• the GTK part

Things that absolutely need to be changed:

• gui: i'm not talking about the GTK code here 'cause it should be compatible, but some other code in the gui was only designed for linux
• some libs are also only crafted for linux, don't forget to find equivalent packages for xlib & any other linux only packages, on windows the Windows API python package should do the trick, but i have no idea about MAC OS
• may also need to check threads (even if the most of threads use functions from libs)
