Express or Connect integration

Due to express >= 4 changes, we need to pass express-session to the function easy-session-file-store exports in order to extend session.Store:

var session = require('express-session');
var FileStore = require('easy-session-file-store')(session);
    store: new FileStore(options),
    secret: 'keyboard cat'
