Improve Org HTML postamble

- If author is not specified, Org retrieves it from email. Usually email is like
  First.Last@domain.com. So Org derives the author to be "First.Last". This commit
  replaces that dot with a space.. so the auto-derived author name is now "First
  Last" instead.
- Earlier if date was not set in the document (No "#+DATE") keyword, or if it
  was set to nil using "#+DATE:", the let-bound date variable was still set to
  an empty string. This commit fixes that.
