src: add support for direct command executionv1.3.2-25

Update live shell run mode for the new REST API interface.
Evaluate the "inline" field to diferentiate between execution of
script in /opt/opengnsys/shell/ and a cmd execution.

Remove usage of echo argument of the API REST.

Update Windows and Linux mode for direct command execution.
Set OutputEncoding environment variable to 'utf-8' in Windows to
unify the encoding of stdout for the invoked programs.

Decode stdout to utf-8-sig to remove potential BOM.

While at this, remove strange legacy ;|\n\r terminator.
