Major Description
The attached diff contains cleaned up html/jsp code for the petstore UI. I've tried to use consistant style sheets across the site. I've also done the following:
1) Added a unique title to each page using <netui-template:setAttribute>
2) Reworked the top nav bar to include a different nav bar for account management
3) Added some arrows to make the checkout process seem more like a wizard
4) Fixed existing bugs in login, set inventory quantity, and checkout.
5) Updated the HTTPUnit tests to match the new UI and to check for the bugs just fixed.
