* :with_comment option is flag
* It should use `true?` instead of `fallback`.

https://github.com/thoughtbot/factory_bot/blob/master/NAME.md

* Hook up with-comment option to rake tasks and CL.
* with_comment option handles commentless columns.
* Style fixes.

* Refactor AnnotateModels#get_model_files
* Add the tests for `AnnotateModels#get_model_files`
* Remove unnecessary `reject` call

Fix #436 where extra line break is added when using windows CRLF (#490)

* Fix InstallGenerator to require annotate
* Fix README

* annotate --routes modifies only routes.rb

This change is a proposed solution to #357 and an alternative to the already proposed solution #361.
In #361 it is needed to call `annotate --routes --ignore-models` to achieve the same as in this change with only `annotate --routes`.

* Call eager_load only when models are included

This to prevent activerecord model errors when using mongoid for example and calling `annotate --routes`

* Drop support of Ruby < 2.2

* add show_complete_foreign_keys as setting

* test for show_complete_foreign_keys setting

LoadError does not descend from `StandardError` so the fallback loading is never invoked.
```
>> LoadError.ancestors
