Integration of Mike Alsup's excellent form serialization code. The benefits are as...

- New method: .serializeArray()
This returns an array of name/value pairs representing the contents of a form, or individual input elements.
- Enhancement: .serialize()
The results are correct now (as opposed to the mess from before), and allows you to serializes forms directly (rather than just the input elements).
- Enhancement: .val()
This now returns the correct value when dealing wih selects. Additionally, when dealing with multiple selects, it returns an array of values.

Based upon Mike's code:
http://malsup.com/jquery/form/comp/form.js

and test suite:
