[TASK] Move language selection after mode selection in page module

The page module has currently two different modes, the layout and the
language comparison mode. To improve the usability we are moving the
language selection after the mode selection. This will help the user
to understand the context of the language switch better.

In addition we are improving the naming on the modes.
-> Columns -> Layout
-> Languages -> Language Comparision
