Endpoint configuration as Map

This patch rewrites the endpoint configuration format to be a map.

The problem here is, that a list of endpoints cannot easily be used with layered
configuration, where a part of the configuration lives in the XDG config home of
the user and the rest lives in the repository.

With this patch, the endpoints are configured with a map instead of an array,
which makes it less complicated to overwrite.
The name of an endpoint is now the key in the map.

A type `EndpointName` was introduced to take advantage of strong typing. Thus,
the patch touches a bit more code to adapt to the new type in use.
