Add first release of AWS plugin

Tools for working with Amazon Web Services:

* Templates for saving a TiddlyWiki as a single JavaScript file in a
ZIP file that can be executed as an AWS Lambda function. In this form,
TiddlyWiki is a self contained single file containing both code and
data, just like the standalone HTML file configuration
* Commands that can be used to interact with AWS services, under both
the Node.js and Lambda configurations of TiddlyWiki
