Cleaned up the header and added links to sub pages

For example we use the following code to load a sub
page:

	$('.projects').live('click', function() {
		console.log('click on projects button');
		$('#page:first').empty().load('blog.html');
	});

this will load the 'blog.html' page when the user
clicks on the '.projects' item.
note that we clear the #page container first!
