Subject: [PATCH 1/4] Serve jQuery from cookie-free Google APIs

jQuery.com uses Google Analytics and so sets a cookie when you visit
the site. When you request jquery.js from its CDN, code.jquery.com,
you take a hit from sending your previous GA cookie in the request.

Google Hosted Libraries[1] and googleapis.com never set cookies.

Subject: [PATCH 2/4] Load Twitter widget async, prevent SPOF

Twitter's widget library[1] provides an async snippet to inject the
script tag later. Since widgets.js came before the local JS, if
twitter.com took long to respond it would prevent subsequent
synchronous script tags.

Subject: [PATCH 3/4] Add protocol for jQuery to work when accessed as file

URLs without protocols get "file:" prepended when their document is
loaded as a file. Make sure the docs can always be opened by
specifying a protocol.
