ssh timeout option in preferences

I usually leave all my windows open when going from home from work. When I want to use the app again it takes about 60 seconds for postico to realise that the connection is gone and to reconnect. This is most likely due to the ssh session stalling and maybe there could be a preference to adjust this.
That is if there is a way at all for you to control this.
I don't think there is a timeout value that would be a great fit for everybody, since it depends on your connection and general network flakiness, so a preference might be a good fit.

No files, tests, or entry points are named. Start by locating the SSH connection and preferences code, then determine whether the timeout is configurable; done means a user-adjustable timeout is supported and the delayed reconnect behavior is covered.
