Tray icon should be enabled by default, no need to make it unnecessay complicated to use.

Not sure if we can do this in a plugin given the requirements for running in main thread and blocking. Might have to be just built in if we add it.

Changed it to threads. It's ugly though since there's a dependency between TrayIcon and Manager. tray needs manager for its shutdown and reload config methods, and manager needs to call tray_icon.stop() when it shutsdown...

@gazpachoking @paranoidi any ideas on how to make this nicer?

Seems tests are failing since by running pip-compile on a mac, it compiled so mac specific deps. I guess in this case we need to add the higher level package (pystray) directly to the requirement.txt file and let it resolve on the client machine.
This will be a problem with future pip-compiles though...
