Make the new attr/prop changes pass the test suite (in Webkit). There are still errors in IE.

Browse source 
+ Added hooks for selected, checked, readonly, disabled to removeAttr if set to falsey

+ Removed all attrs from attrFix, these aren't needed for setAttribute

+ If prop is used for class, do we want a propFix for class?

  - We could just assume the user should know to use className with prop.  I've done the latter for now.

+ Created tests for $.fn.prop and $.fn.removeProp

  - Actually all I did was change broken attr tests to prop where it made sense.
