Add release script

What the title says.

This is a bash script that will do everything for you:

 * Gets the version and the public maven repo path via param
 * Prompts user for confirmation
 * Builds the project
 * Executes the maven deploy task
 * Commits and pushes the changes to the public maven repo
nope it creates whatever file extension is neccessary, at the end of the day an aar and a jar are both just a zip. If oyu read the blog :) it just uses the gradle maven lpugin so you can do this same command it's just that you get the bonus of the wrapper rather than relying on the persons personal setup (i.e. setup agnostic)
