Add an Alexa Skill

[essenbee]

I would like to add an Alexa skill has an API endpoint to this project. The skill would enable users with an Echo device to ask questions such as "Alexa, ask DevStreams when devchatter is streaming next?", and receive a verbal response based upon the data held in the DevStreams database. I would like to develop the concept on my own Codebase Alpha stream, and then submit a PR to this project.
