App indicator does not show in icon tray

[acotis]

This code is supposed to display an app indicator in your system's icon tray. It is supposed to be white when the script is not "listening" to inputs and red when it is listening. This lets you always see at a glance whether you've accidentally left it in "listening" mode. Unfortunately this feature is currently broken on some distros because support for the libappindicator library has been discontinued in favor of the libayatana-appindicator library, and the pystray library (which this code uses to manage the tray icon) doesn't support that yet (but they are working on it). When it does, the fix will be to simply change the "run" recipe in the Makefile from:

run:
	python3 main.py #| python3 trayicon.py

to:

run:
	python3 main.py | python3 trayicon.py

E.g., simply uncomment the second half of the line.
