Hexchat - Really noticable message notification plugin

bignotify.py

import hexchat

"""
Restore and raise the hexchat main window whenever a message is received.

To get this working on a recent Ubuntu GNOME environment, you also need to:
    - Install the Firefox GNOME Shell Integration extension.
      https://addons.mozilla.org/en-US/firefox/addon/gnome-shell-integration/
    - Install the GNOME "Steal My Focus" extension.
      https://extensions.gnome.org/extension/234/steal-my-focus/
    - Copy this script to ~/.config/hexchat/addons.
    - Load the plugin from the HexChat menu.
    
This works well alongside the TopIcons Plus extension
(https://extensions.gnome.org/extension/1031/topicons/) which somehow keeps
the newly raised window from stealing focus (when used to minimize)

TODO - implement a strategy to raise hidden without ultimately stealing focus.

Logouts/reboots may be needed between steps.
