Subject: Correctly handle multiple inline scripts, multiple intrinsic events,
 whitelisting/blacklisting and listing in the panel.

Before this, only the first inline script would get properly handled. This also corrects script comments for href="javascript:foo" types of scripts, which cannot get comments added in to state the result of LibreJS parsing.
