app.boot does not work in dev/prod environments

Hello @dpup, 

When moving the middleware into matador, ``app``
was not properly moved to ``connect``, thus failing
when NODE_ENV is either production or development.

Please review the following commits I made in branch 'vinny-fixing-connect-errorhandler'.
