Add pagination fow news

[splattater]

With increasing number of news posts we want to use the pagination feature.

Paging implemented in our theme [1] uses links to existing pages.
I will have a look together with @white-gecko if it is possible to generate paginated pages containing a distinct number of news and then generate pagination and the links with help of the total number of existing news.
