Create Morphir launcher script for bash.

[DamianReeves]

Feature Request

Create a bash script that can acquire the "morphir launcher" from Maven and start it up with the appropriate Java options similar to maven-wrapper, gradle-wrapper, or millw.

Description of Problem:

There needs to be a way to actually acquire the morphir tooling.
Maven has a decent story around this where it uses the maven-wrapper as a means to use shell scripts to acquire the maven application.
Sbt also has an sbt-launcher which is a lightweight application which setups sbt for execution and pulls down the rest of "sbt proper".
We will use the morphir-tools-launcher jar as a lightweight tool for acquiring the morphir tooling and getting us started. This issue is around creating a shell script that can pull down the morphir-tools-launcher from a maven/ivy style repo like Maven Central or an internal Artifactory instance.
