Blog entry should contain "previous / next entry" links

Take for example:
https://reactos.org/blogs/ntfs-write-support-gsoc-week-8
you can not view week 7 without having to navigate back to overview
https://reactos.org/blog/49142
but here you have to decide whether you either want to navigate(prev/next) or read the full entry.
Choosing "read more" will immediately take the navigation buttons from you.

Proposal therefore:
Add prev/next to every expanded "read-more"-view.
