Page display pointer: Considerably improved accessibility
- Updated pointer to move within content DOM so that you can back-focus
  into the pointer if desired.
- Added new "Section select mode" which toggles focusabiltiy for main
  content sections, with ability to show pointer via enter press on
  these.
- Updated pointer with proper input/button labelling.

Tested via orca screen reader on Firefox/Fedora/Gnome.
