Added some stuff to TODO.
Removed .html extension from nav in default template.
Added google fonts CSS and modified default.hs

Added literal CSS to default.hs and modified the code so that it outputs that
css before the CSS rendered by Clay. There may be too many fonts currently.
Added CV to site.

Added code to site.hs to match cv.md, and updated the default template to
display it in navigation.
Added author metadata to post.
Changed title in default template from Hakyll default.
Fixed wording in about.md
Cleaned up CSS.

Cleaned up CSS a good deal. Still some bugs but the site doesn't suck like a
vacuum.
