Consider generating dictionary.yml from handler package

[alileza]

Is your feature request related to a problem? Please describe.
Writing go code based/generated from yml file feels wrong, since it's a go application. Go (executable binary) should be the source of truth.

Describe the solution you'd like
It would be nice to have dictionary.yml generated from handler package itself, maybe consider using how godoc.org steal from code comments to get detailed documentation.

Describe alternatives you've considered
Re-structure the handler packages to be godoc friendly, that way, the handler/action documentation can come from godoc
