Centralise all form based client side functionality

Found a better way of doing this, instead of creating partial which would of been kind of naughty, we can use the jquery.include function to include the necessary js files just before we setup our new events after a successful form submission.

Need to go through all forms and make sure this functionality does not break anything

All basic forms seem to be working fine, we'll need to create the following acceptance tests to make sure that these bits of functionality do not break when we add new JS functionality

Now created acceptance tests for the following features:
ordering button
info and summary headers
flash messages
hover sidebar

Will need to work on pagination and making sure the above functionality also works when pagination is being used.

Features to cover:
pagination

Scenario now covered.
