Add new option to script-get command to control whether apps are opened with or without data

[mountaindude]

When exporting app scripts the app in question is first opened, then the script retrieved.

In current version (=3.16.0) of Ctrl-Q, the app(s) will be opened with data. This works, but results in significant load on a Sense server if lots of app scripts are to be exported. For example using a PowerShell or Bash script to export all apps in a system, or all apps matching some tag.

A better option is to open the app without data.
This would also solve a problem with apps using section access - these may not open properly if the wrong user is used when calling the Sense APIs.

Proposed change:

• Add a new option --open-without-data, with possible values true and false.
• Set the default value to true.
• If setting this option to false Ctrl-Q will have the same behaviour as current version.
