Allow to use existing infi.systray instance as tray icon to spawn notifications

[omriharel]

https://github.com/Infinidat/infi.systray is a great helper to allow system tray options for your Python app.

Would you be willing to support spawning notifications from an existing tray instance to avoid two separate icons showing up?
