Add a Plugin for VSCode

[masukomi]

Following the documentation add a plugin (in a separate repo) for VS Code that speaks to this server ( Simple JSON API calls), allows users to display, edit, and delete comments provided by the server.

If you're comfortable with Lisp the emacs plugin may be a useful guide, but it'll probably be more straightforward to just read the docs and implement it without looking at other codebases.

NOTE: this would be created in your own separate repo. not in this one. ;)
