Converted JS hamburger button menu code to use standard JS only, no jQuery.

Temporarily lost the animation with this change: I'm checking this in separately to make the difference between this and the jQuery version clearer.

Not sure how portable it is yet; I wouldn't be surprised if it broke on old IE, since we're using xhr.onload instead of the horrid mess that is xhr.onreadystatechange. check-in: 113ba3d9 user: wyoung tags: js-hamburger-menu

Reverted [59c7ca0509]: drh says we can't use jQuery. Also, there was a syntax error that sent all hyperlinks to the honeypot in some conditions. check-in: 5a62b395 user: wyoung tags: js-hamburger-menu
