Better empty state

[guillaumealgis]

Today we only display a blank view, without any info.

Inspired by #458. We should probably show the repo URL if it's not the default one and no package was loaded.

Inspiration:
https://github.com/dzenbot/DZNEmptyDataSet
http://emptystat.es/

Yeah I think this makes sense

If only DZNEmptyDataSet had AppKit support! Would love to contribute to this initiative for sure.

I wouldn't like to take on an external dependency for empty states (we don't have any dependencies aorn as having them in Xcode plugins is kind of difficult at the moment but help with implementing this would be more than welcome!

[dzenbot]

Oh yes, wasn't planning to port the lib to Mac either. I meant implementing it 😇
