Refactor and advancements

- Drops mailController, centralized in UserController
- Adds views folder for change_password
- Improves PromiseRouter to support text results
- Improves PromiseRouter to support empty responses for redirects
- Adds options to AdaptableController
- UsersController gracefully fails when no adapter is set
- Refactors GlobalConfig into same style for Routers
