Move pager inside searchresults div

Move pager inside searchresults div

The pager is part of the searchresults page, but can't be styled
easily like the searchresults div container, because it's outside
the container. The pager should be in one block element with the
serach results.

This enables (e.g. extensions) to add content to the right side
of the search result page without having the problem with a pager,
that can't easily moved with CSS.
