To-Do List App Upgraded!

This is my version of the To-Do List App that we make with Andrew Chalkley in his JavaScript course: http://teamtreehouse.com/library/interactive-web-pages-with-javascript.

It is located here: http://www.marcusparsons.com/projects/todolist/index.html

I changed a lot of the styling, but more importantly, I added persistence using HTML5's localStorage, which means that items in your to-do list don't go away when you close the page or the browser. I added the LZ-String compression tool, as well, to maximize the amount of storage available. I also added some compatibility layers for dealing with IE, and some extra helper things such as the ability to press Enter in the Add box to add a new to-do item, and press Enter in the edit input field to save the edit of a to-do list item (no pun intended).

Let me know what you think!
