Don't pass crap to Html::input.

If the user has not signed off on a revision, the previous code used
to generate invalid HTML like:

<input id="wpSignoffFlags-inspected" ="" type="checkbox" value="inspected" name="wpSignoffFlags[]" />

Note the equal sign followed by two double quotes after the id and
before the type attribute.

Also bumped the version number a bit, because I like meaningful,
accurate, up-to-date version numbers.
