Postscript names not matched in PDF import

@joneuhauser reports that the names often used in PDF and Postscript that we currently fuzzy match to installed fonts can be found using the following:

they are called the "Postscript name".

for file in /c/Windows/Fonts/*.{ttf,otf}; do fc-scan --format "%{postscriptname}\n" $file; done

This information should be used to improve the font handling in both PDF, postscript and other importers that have the handle font names.

These names should also be made available in an action so the AI importer can use them to match font names too.
