New homepage layout, styling changes, nav update, new include

New homepage layout loses images in exchange for list of projects. May
include thumbs in the future.

New styles for h1.page-header.

Update the nav to say "Home" instead of "Work".

New include used for showing a single post to show on homepage. Thanks
