Minor updates to IG scripts

- Update updatePublisher scripts to have more clear options for prompts. Add space after prompt for clarity.
- Update genonce.sh script to not depend on wget. Instead use curl to check internet connection since it is used in updatePublisher.
- Update gencontinuous scripts to reference relative genonce scripts.
