Redone how JS libraries are used.

Including using Google CDN jQuery now with local fallback, moved
Modernizr into its own file and request instead of compiling libraries
into my single JS file.

Updated <head> and footer accordingly.

Also mega comments in the <head>!
Gist CSS.

Stripped out most of the GitHub Gist CSS overrides, not doing that
anymore.
Iconzzz

Renamed the 144px icon to match the others.
Nav

Markup tweak, I think?
Google verification

Moved Google WM Tools verification code.
Comments in analytics code.
