When attempting to set special characters(\r or \n in particular) in variables via the execute-app-arg they can be stripped out by the ESL header parser. This can cause issues when trying to format sip_multipart variables that include multipart headers.
Overview
Add a boolean parameter ForceBody to the Execute command. This will force the app arguments into the body even if it's less than 2048 characters.
Make all Set/Export/Push commands force their arguments to the body to ensure nothing gets lost.
Update the unit tests to match that the arguments are now in the body of the message.
