Fix duplicate frame-message, tangled files, package.lisp corruption

- Removed duplicate frame-message from communication.org (was in 2 src blocks)
- Fixed communication.org :tangle directive (was wrongly targeting package.lisp)
- Added (in-package :opencortex) to engineering-standards.lisp
- Retangled package.org, communication.org, engineering-standards.org

Tests still not running - investigation in progress.
