explicitly ask user for julia path if not automatically found

by using something like dialog.showOpenDialog. Not sure how necessary this is, but might be useful.

It's a good idea, although it might be less useful on OS X where .app folders are trickier to get into when you don't know how. And on Windows I expect most people will stick to the default install location. I could see it being useful on Linux though.

Given that we don't handle multiple julia installs gracefully yet, this might be useful in those cases (and also on Windows) anyways.
And could we set something like the .app folders as the initial path, i.e. could the user navigate through them then?

[MikeInnes]

OS X just makes that a bit tricky – you have to right click the app and explicitly "open" it up, which is easy enough but just lengthens the instructions that little bit.

One option might be to have a choose julia menu option that lets you do this and point people there.

Very confusing for a newbie. Atom sees uber-juno as installed. And that's about it. How do I get Atom to see uber-juno as an "installed" package??
