Overall cleanup.
1. CSS is now in {% block style_base %}. Moved Javascript to the bottom of body, to {% block script_base %}.
2. My file js/todo-ui.js now is loaded directly before it is called, also at the end of body. The main list is now in <ul id="main_item_list">. Nothing inside it originally, and no extra divs around it.
3. Slightly restyled the group of four buttons (create new, sort...).
Removed the $.sortable() jQuery UI plugin. Now items cannot be drag-and-dropped. Also, now we don't need jQuery UI any more.
