Standardize WWW: tags a bit more:
1. Remove white space from the beginning of lines
2. Make the canonical WWW the last line of the file
3. Remove lines to the effect of, "More information can be found at..."
that's the stated purpose of the WWW: tags in the first place.
4. Change secondary WWW: lines to use other text to avoid confusion
While I'm here, remove some more useless Author: lines, and some
prepended white space to other lines.
