AMD64 Have a way for the user to disable chatty from starting on boot

Currently Chatty is set to start on boot.

While this is understandable on a phone, as you need it to get SMS when they received, not when you open the app.

But that is not necessarily the use case for amd64 laptop users. Some laptop users might not want to be disturbed by messaging apps automatically opening on every boot.

Suggestion: have a user facing option for the user to enable/disable auto starting chatty on boot. But the default could be enabled, something that the users opt's out of.

And yes, I know it is probably not easy
