Add Better Snippets

[zardoy]

HNY! I've just made a new productivity extension.

Name of the extension you are adding

Better Snippets

Why do you think this extension is awesome?

Why not? It let's you create more powerful snippets, and I think even more powerful than live templates. I don't expect from other extensions web support. I'll probably add tests if I receive more feedback

You can also look at example usage

Make sure that:

• [ ] Screenshot/GIF included (to demonstrate the plugin functionality) Not sure what screenshot I should include, everybody knows how suggestion widget looks like.

• [X] ToC updated

Other changes are from VSC formatter. I don't it's worth to add introduce them as separate PR, so leaving them just here.

You can look at my twitter for more gifs demonstrating how cool this extension is!

@viatsko thoughts?

We are trying to have more widely adopted extensions on the list, 35 installations wouldn't be enough.
