Kh redesign start

Created a new "Homepage" for the site that features a big search-bar, and that's pretty much it. The reasoning behind this is that it gives the user one clear call to action and allows us to show more content above the fold on the results page (b/c we move the search bar into the nav). 

I created separate html and css files (redesign-start.html and frontpage.css). We can probably find a better naming scheme once we replace index.html Drew mentioned that we'd have to be able to post to these pages if we broke them up.
