Make job "script" steps have a name

• Issue Type: Improvement
• Rundeck version: 1.4.2

Issue:

In a job, "script" steps currently just say "Script: N lines". Without expanding each script step, and even after, hard to know what that step is supposed to do.

Suggesting "script" steps have a name, and when viewing the steps, this name is displayed.

For instance, now I have a job that has:

1. sudo /etc/init.d/tomcat stop
2. Script: 9 lines =>

(=> is the graphic to expand the script)

Step 2. is a short script to check and wait for tomcat to completely stop.

If I had the name field, I could say "Wait for tomcat to stop", and then the job step list could look something like:

1. sudo /etc/init.d/tomcat stop
2. Script: Wait for tomcat to stop (9 lines) =>
