Moved the page resizing from SwLayoutFrm::Format to
SwPageFrm::MakeAll and calculated the new page height
more accurately based on the content (stolen from
the browser-mode height calculation, to be refactored).
This fixes issues with repagination with certain contents.

Removed unnecessary ToggleLayoutMode calls and
prevented clicking between pages in single-view
mode to jump the cursor.
