Continued with project:
- started to rewrite to a more flexible solution: a general item basket that will accept OrderableItem instances
- added parameter "type" for upcoming basket feature
- renamed "choose" to "id", this old thing will be completely rewritten
- added new script "add_item.jsp"
- added some more CSS for footer navigation
- Accessing the JSPs directly may not be a good idea, better is to have aliases (more about that later)
- added generic interface OrderableItem and BasketItem class (unfinished)
- added links in footer.jsp for new pages "privacy.jsp", "terms.jsp" and "imprint.jsp"
- using JSTL "fmt" for formatting currency values
- added project's license "GPL3"
