diffs: compare overhaul.

- made compare and commit range pages more consistent with other commit diff pages
- removed mergerly, closes  #4665. Old diff2way is replaced by new diffs with
  side-by-side mode.
- cleanup button behaviour on compare page. Added help text and
  generally improved UX
- switched file-diffs to compare page with file filter. Part of  #4000
- added collapse/expand commits buttons in compare views.
