Remove loop view until a maintainer is found

[Joern Ungermann]

The loopview feature ties closely into a website that is not under our control. It is difficult to use it for something else.

I propose to remove this feature until somebody wills to maintain it (i.e. repair it, document it and provide unit tests). This will confuse new users less.
