@tonybaloney this pull request should be ready for a review.

File imports will be another blocker to #276 in which browser extensions cannot support the fs module.

Please have a look at https://www.npmjs.com/package/vsls with example https://marketplace.visualstudio.com/items?itemName=lostintangent.vsls-whiteboard as APIs for sharing information inside a VS Code live share.

Does vscode's built in file system work in the browser?

[tonybaloney]

I've made a couple of changes:

• The exported files are JSON instead of the text format. The array type was already serializable and now it'll handle the formatting issues
• The input colour is validated to avoid the mystery pet bug
• The exported file uses the "untitled" protocol which opens it in a tab in VS Code ready to save, but without having saved the files so the user can rename it
• The exported file name has a unique-ish number in it to avoid collision
• The import action uses the open file dialog so the user can pick the file, instead of assuming it's named a certain way and inside the workspace (since the workspace might be a project they're working on and nothing to do with pets).
