Update of the release notes for V4.3

This updates the V4.3 release notes.
1) The release notes text is moved into a newly-created directory ReleaseNotes
2) Three images for the release notes are created in a subdirectory within
   the ReleaseNotes directory.
3) Light editing of the complete text of the release notes was done.
