Tab JS optimizations:

- Use jQuery.live so that even if tabs are ajaxed in they still work.
- Don't use DOM ready since this JS file is already at the bottom of the page.
- Remove selected class only on sibling tabs.
- Don't add a selected class on selected tab if it's already there (avoid hits to the DOM).
- Avoid using $(this) a lot, and instead use a saved reference, as you're creating a new jQuery object each time.
- Use '$' in front of jQuery variables so that you know they are jQuery objects.
