Add argument to nowoif scriptlet

When a 3rd argument was provided, the scriplet would
log information related to window popup operations,
regardless of the value of the argument.

The 3rd argument is now parsed in a formal manner. It
is meant to be one or more space-separated tokens which
are used to fine tune the behavior of the scriptlet.

Tokens:

log:
  Cause the scriptlet to log information regarding
  how window.open() is used by the page on which the
  scriptlet is used. Useful only to filter creators.

obj:
  Use an `object` element instead of `iframe` element
  (default) as a decoy to be used in place of a popup
  window, when the page requires a valid `window`
  instance to be returned.
