"Version request URLs should always end with a trailing slash (/). If the slash is omitted, the server may respond with a 302 redirection request." -- The current v1.1 spec

So the real bug is that it should be a 302 response, not a 500 error

    Redirects requests from /v#.# to /v#.#/

    Added an APIMapper to catch routemaps when the url is '' because routes.Mapper returns an error if this is the case but we want a redirect
    Fixes bug 865585
    Related to Routes issue: https://bitbucket.org/bbangert/routes/issue/37/mapper-and-false-url
