Performance enhancement

[nathanfallet]

When editing big files or having a lot of logs in the console, the editor starts to be slow.
User interface needs to be optimised.

Possible solutions:

• Use new AttributedString capability to render console (edit: it's even worse)
• Remove Kingfisher and use new Image API (edit: useless)
• Use Runestone for code editor (when available, to replace Sourceful which is slow)

@simonbs Any news about Runestone as a Swift Package?

I hope that it won't be too long. For the most part I consider the Swift package to be complete but I'm waiting to release it until I'm also ready to release my Runestone text editor app.

Update: Runestone should be coming on May 5th!
