investigate better event management

[bboyle]

1. test use of .delegate() to bind events. does it remove the need to unbind and rebind?
2. test jquery 1.7 .on() event

[bboyle]

.delegate() works but appears to execute after any other handles that use .bind() which could be problematic.

[bboyle]

IE6 may not work with .delegate()—further investigation required.

Pattern to test:

$( document ).delegate( 'form', 'submit', submitHandler );
