Subject: [PATCH] [WRT] Add chrome extension sample

This adds chrome extension sample for reference.

The extension has chrome extension style manifest.json that specifies
name, background, and contentscript.

It alerts popup when click event is emitted on web app.
Also, contentscript and background communicate each other via IPC
that can be checked by inspector console.
