WhiteListSanitizer removes unknown tags instead of escaping.

Reported by antonmos | August 27th, 2008 @ 03:45 PM | in 2.x

Quoting the comment in santizier.rb for bad_tags member: "# Specifies a Set of 'bad' tags that the #sanitize helper will remove completely, as opposed to just escaping harmless tags like <font>"

However, the current code completely removes all unknown tags regardless of bad_tags set.

This is a problem because users may want to use text enclosed in < and > characters in their content (i.e. forum posts) and simply removing them is confusing and (unpleasantly) surprising.
