Had to make some design concessions. ViewType can no longer be distilled using the routeMatches, but must instead now be provided by the more static routeConfig. This way, the chosen ViewType shall always be one that is chosen by the developer.
Also added some other smaller features, as requested by other components and plugins:
- Now added a 'namespacePrefix' for Router::defaultCallable. Allows for the usage of Views and Controllers from a namespace different from '\\Application', from within the router sphere.
- Added a $routes =  parameter to Router::route(), allowing the developer to bypass the global routes list if necessary.
