modernizr.js is not modified because it's not our code.
En passant fixes:
* Delete two scripts that depended on a Yahoo service that
appears no longer to exist.
* The PhantomJS website no longer has a leading www.
* One script needed correction to *work* in strict mode.
* One script would only exit if a page loaded successfully.
(There may be other instances of this problem, this is the
one I noticed.)
