tokenField lookup in req.params

[phof]

It allows the tokenField to be part of the URL path, i.e.:

passport.use(
  new MagicLinkStrategy(
    {
      secret: 'some-secret',
      userFields: ['email'],
      tokenField: 'accessToken',
    },
    (req, user, token) => {
      // sendToken
    },
    (user) => {
      // verifyUser
    }
  )
)

...

app.get(
  '/auth/:accessToken',
  passport.authenticate('magiclink', { action: 'acceptToken' }),
  (req, res) => res.redirect('/')
)

@vinialbano, thoughts?
