Nova RSpec Runner

This extension was purely to learn about Nova and should not in any way be considered "good". I made this the first day of trying Nova and was trying to port an extension I use on VSCode.

Findings

• Cannot access user terminals (makes sense with the whole entitlements thing that being able to write to a user's terminal would not be safe)
• TreeView's are the only visual panel for long content you can add other than opening a document
• Line numbers are incredibly difficult to determine when Nova only gives you character count

Publishing

• Update RSpecRunner.novaextension/CHANGELOG.md with the next version number and a description of changes.
• Update the version number in RSpecRunner.novaextension/extension.json
• Run npm install
• Run npm run-script build
• In Nova select Submit to the Extension Library... in the Extensions memu
