Created a key value model for Tweakable Values and the like
Changed order of config.ru, so the config variables are set first, then the classes are loaded. Also fixed two unnecessary requires in the model loader.
Removed example route. Added key value model, made calls possible to get values
No need to set a default format
Added stubs for the backend model editor.
Merge branch 'feature/tweakable_values' into develop
Added simple user authentication from within the API
