ScriptResourceModel plugin can't use script-args and script-interpreter

• Issue Type: Bug
• Rundeck version: 1.4.2
• JDK Version: 1.6
• Server OS: Mac OS X
• Install type: Jar

Issue:

There is a bug when you specify script-args, and the script-interpreter.
Rundeck is passing the whole filename + args as the filename to the interpreter.

Caught: java.io.FileNotFoundException: /Users/alexh/rundeck/libext/cache/groovy-script-plugin/mock.groovy -u http:/localhost:8080 -t Server (/Users/alexh/rundeck/libext/cache/groovy-script-plugin/mock.groovy -u http:/localhost:8080 -t Server)

Here is a plugin.yaml showing the desired syntax:
