Add ability to start PHD2
Maybe it's a good idea to start PHD2 if not yet started when a profile with PHD2 guided is started?
The user can specify the location of the executable. We can use QProcess to manage it. Ekos should check if an instance of PHD2 is already running. Maybe we should run connect first and if that fails, then that means we should start an instance of PHD2?
@edejouhanet @lancaster What do you guys think?
