Extract all settings into `SettingsHandler` object

This enables the user to straight forwardly change all application settings via command mode.

During the implementation of this change I discovered that the way I was passing around `StateHandler` and `SettingsHandler` instances using properties was unnecessary. If all object instances are created in a common hierarchy they can access each other by their `id` property - i.e. `settings` and `mode` are available to the whole application without property trickery.
