$.extend($.support, {

files: typeof FileReader != 'undefined', cache: !!window.applicationCache, webdb: !!window.openDatabase, geolocation: !!navigator.geolocation, history: !!(window.history && window.history.pushState && window.history.popState), messaging: !!window.postMessage, microdata: !!document.getItems, serverSentEvents: typeof EventSource != 'undefined', localStorage: !!window.localStorage, undo: typeof UndoManager != 'undefined', websockets: !!window.WebSocket, webWorker: !!window.Worker

});

Adds HTML5 feature detection to jQuery

[dmethvin]

We should weigh the cost of running this code on every page; right now nearly all the jQuery.support properties are used by core itself.

Using something like Modernizr is going to be a more scalable solution for something like this. http:/modernizr.com

[dmethvin]

Per the docs for jQuery.support, none of these feature tests belong in core unless jQuery core itself needs them. Modernizr is a better general solution.
