The React <Page> component should take a 'config' parameter instead of 'componentMappings'. The config parameter is an object, and for now supports only one subproperty - 'componentMappings'.

Update examples as well.

Reason:

The amount of configuration for the SPA libraries will definitely increase as we support additional features, such as personalization, multilanguage, AB-testing and so forth.

It will save us and project developers trouble if we implement a 'config' argument now which can be the vehicle for the 'componentMappings' , and easily support further parameters later.

This is a standard pattern for js libraries to accept all configuration in one JS object.
