configuration: Allow including multiple files into one mapping.

Browse Source 
The key for 'include#' can now be either a scalar or a list.
A scalar triggers the same behaviour as before.
If the value is a list it must be a list of scalars (filepaths).
The paths will be loaded and merged in order, and finally the resulting
dict is included into the current scope.
