Don't open script editor when connecting signals to existing methods

[passivestar]

When you create a new method it's great, because you want to implement it, but when you connect to an existing method I can't think of any reason for that to happen. I keep minimizing vscode

IMO should just not happen at all for existing methods, but if somebody can think of a reason for that to happen then maybe could at least be configurable:

Almost the same idea with the difference to not switch when the method exists, as opposed to at all

I'd say, from the conversation on the other issue, that this should be a setting, not absolute

Maybe a three-way setting? Always open, open only on creation, and never open? I can certainly see myself using the middle option most of the time, and from the other conversation it seems that is the current intention.
