Update to editorial notes and change notes in ttl file

[davebrowning]

in line with #919... and #920.

Remove editorialNotes marking work in progress
Align change notes with the work in #919

[davebrowning]

This should only get merged after #919 has been merged.

Question: should the ttl file have an entry for dct:location since we have one for dct:PeriodOfTime?

[dr-shorthair]

My view is that we should mention every class and property that is 'recommended for use'.
WHere these have usage notes or definitions in context that vary at all from the originator's, these should also be included as skos:definition and skos:scopeNote.

I agree with @dr-shorthair's point.

[davebrowning]

Thanks - I've done that now (though since I don't have any support for ttl syntax someone should have a check....)

I also think that this lines up with #919 (as it did before) but re-checking all the notes etc can perhaps wait till its time to merge this.....

[dr-shorthair]

I did a syntax check.
