Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
Especially when rotated and/or mirrored.
It's not perfect but it's close enough to being correct.

(cherry picked from commit bdc371f05720687bdc200274315fd7ca42ba2545)
Schematics, symbols, boards and footprints all get the ability to store
files inside their file structures. File lookups now have a
kicad-embed:// URI to allow various parts of KiCad to refer to files
stored in this manner.
kicad-embed://datasheet.pdf references the file named "datasheet.pdf"
embedded in the document. Embeds are allowed in schematics, boards,
symbols and footprints. Currently supported embeddings are Datasheets,
3D Models and drawingsheets

Also, corrects a minor issue with the text width calculation where
Altium calculates centerline to centerline but KiCad text heights are to
the edge of the stroke font. Need to still do better adjustments for
the various altium stroke fonts
