More granular requires.

This removes the giant list of requires in lib/goliath.rb in favor of letting
each component require the pieces it needs. It also provides new files with
autoloads for the modules inside Goliath, eg, Goliath::Rack. Importantly,
this makes it possible to require 'goliath/api' seperately from
'goliath/application', meaning you can load Runner & API to bootstrap the
server without the magic in Application.
