Fix #7472 and added test for #3113

Browse source 
- Forms with an input that has either name="action" or name="some-other-attr-on-the-form" caused problems in IE6/7.  This is fixed.

- Changed check in $.attr for ret === null to typeof ret === "object" to catch any inputs that are accidentally retrieved in IE6/7, since attributes cannot be set to objects and typeof null === "object"
