add options.strategyName to allow multiple passport-local instances to work in one node.js app;

example code:

    passport.use(new LocalStrategy({ strategyName: 'local' }, ... );
    app.post('/login', passport.authenticate('local', {
      successReturnToOrRedirect: '/',
      failureRedirect: '/login'
    }));

    passport.use(new LocalStrategy({ strategyName: 'local-two' }, ... );
    app.post('/another/login', passport.authenticate('local-two', {
      successReturnToOrRedirect: '/another',
      failureRedirect: '/another/login'
    }));
