Update README.md

Improvements on the boilerplates section
- Pass routing options instead of previous controller name to controller actions
- Add previousControllerName to routing options
- Separate query string from the path and add it to the routing options
- Route#extractQueryParams uses options.queryString or location.search
- Cleanup and comments for consistency
Also pass the routing options to before actions. The return value of the previous action is now the third param (breaking change).
