Subject: Moved main to cmd/web and added routes() method

Started to separate out funtionality: added an application struct and
several methods (routes(), home() and a notFound() error).

At the moment, the application struct does not carry any other
configuration objects or a database pool connection - it is just there
to get the routing going.
