Improve macro recording of scripts executed from Script Editor

[ctrueden]

1. Start the Macro Recorder; record as Macro.

2. Press [ to start the Script Editor.

3. Paste the following script:

   #@ String name
   #@output String greeting
   greeting = "Hello, " + name

4. Switch the language to Groovy.

5. Save the script (e.g. /home/curtis/Desktop/Greeting.groovy).

6. Run the script with Ctrl+R or the Run button.

7. Observe the recorded command:

   run("script:/home/curtis/Desktop/Greeting.groovy", "name=Chuckles");

8. Create a new macro from the recorded command.

9. Try to run the macro.

10. Observe error message:

    Unrecognized command: "script:/home/curtis/Desktop/Greeting.groovy", "name=Chuckles");

Would be nice for ImageJ's run function to support executing scripts via module identifier, in addition to ImageJ1-style short name from the menus.
