Fixing js enqueue

I simplified the js enqueue function. I undid the deregistering of built in jquery, which messes with plugins that use that. I removed the jquery from the vendor dir, because that isn't needed and I pulled the extra function you had to put foundation.min.js into the footer.

I'm going to work through a few more things tonight and tomorrow so it can meet wp.org theme repository standards. It's a bunch of little things. I'm also trying to vertical navigation from Foundation 3. Can't get it to work, even when I solve the console errors, will keep you posted.
