Title: add ability to set data attributes via $(elem).data(obj)

This will allow one to set data attributes like so:

$(elem).data({
foo: 'bar',
lorem: 'ipsum'
});

This is present in jQuery: http://api.jquery.com/data/#data1

I don't know if you all want it included in Zepto or not. No worries if not.
