Feature request: Support non-form elements

[matryer]

I would like to be able to get data from a range of elements, decided by the selector on the active jQuery object.

Some examples:

var name = $("ul li.name input").formalize();

you can currently pull data from within any element, if you're looking to pull data from across a range of different elements, that would be an edge case I'd need to build a test for.
