Productpage

Put javascript and CSS dependencies to /assets/*
- jquery
- backbone.js
- Twitter Bootstrap
Create product.jsp.
Also I added and implemented some tasks to application:
- Add twitter bootstrap styles for the login form
- Redesign product page with apache tiles
- Add ProductController to map requests to product page
- Remove styles.css from the project
P.S Because this branch was forked from springsecurity one and they were developing in parallel mode, some of commits from springsecurity take place in this branch.
