For extension authors: this release adds a fetch API and new observe APIs.

I have added an example inspector item to the @Bike extension that puts these changes together. To try it out fully select a word in your outline. You should see a list of synonyms show in the inspector. Dig into the @Bike extension to see how it works… but the basic idea is fetch happens in the app context. It requires the fetch permission. It sends results to the DOMScript context.

Questions welcome!

• Added fetch (fetch permission) API
• Added outlineEditor.observeSelection API
• Added window.observeFrontmostOutlineEditor API
• Added more editor API for folding and focus testing
• Changed some fields in outlineEditor.selection
• Removed network access in DOMScripts (fetch should always fail)
