syntaxes: mention the original author of most of the syntax files

The names of the authors were retrieved from:

  git log -p --follow  syntax/<name>.nanorc

and from:

  git log -p --follow --all --  doc/nanorc.sample

For some files the original author is unclear, or
the file is/was too small to mention an author for.
