* Treat dist dir as binary, so the line endings are not normalized by git

This allows to avoid annoying behaviour when you checkout repo and already have a diff which can't be reset

* add necessary dev dependencies

* clone should handle circular refs

* fix handling nested allOf and oneOf with partial schema inside

* improve noEmpty test helper

* handle alwaysFakeOptionals + additionalProperties: false

* Fix previously hidden failing test: can't alwaysFakeOptionals recursively

* make npm test do what is supposed to do
