Christopher Allen 1306e41d3b Load playground.html etc. from local http server ...

Unlike goog.provide packages, goog.module modules are loaded using
XMLHttpRequest in uncompiled mode.  Because browsers treat file: URLs
as each being a separate, unique origin, this means that CORS rules
prevent goog.module modules being loaded from a file URL.

To work around this, use the http-server npm to serve the repository
root directory on localhost:8080.

Provide a script so that you can type `npm start` to start the local
http server and automatically open a browser window pointing at
tests/playground.html.

Modify the setBackgroundColour function in the playgrounds to provide
the usual lilac background on locahost URLs and a sickly green one
if using a file: URL, all of which will soon stop working.

(The background doesn't actually appear to be visible in the advanced
playground.)
