Remove obnoxious copyright notice

As requested
Added two new (fake) status codes.  -2, which means multiple <html>
tags and -3 which means none at all.
Fixed two bugs:
      Only verify HTML of HTML content.
      Allow crud in HTML tags.
Merge branch 'verify_html' into 'master'

Respect the fact that HTML contains newlines and that content-type is
presented as lower case.
Fixed ordering of status codes.
