Add line break to streamed writing

I am starting to add line breaks. This makes the dumps a lot better in
terms of parsing. Also updated the repository input format.

Extend the list of repositories heavily

I have research for more CKAN powered open government data portals. I
have added my results to the list. Unfortunately, some CKAN instances
are running on version 1.7 or below.

I have to reimplement the use of API version 1 to make harvesting
possible again. Until then, these entries will be kept disabled.
