- deleted unused code blocks
- updated based on PR review
- added `readConfig` to lib/util.js to read configuration (either JSON or YAML format) . probably the rs.config add-on can be refactored to use this.
Restored `page.routes` as its required on `ac.url` add-on.
- Restored `route-maker` as `ac.url` add-on depends on it.
Fixed typos in log messages.
