Adding Twitter Client adapter factory

The crux of this change is to easily use the Twitter4J API using Cloud Service Configurations. With the adapter factory, you can adapt a page or a configuration.

To illustrate this, I also included a status page, accessible under miscadmin which outputs the current rate limit status of each configured Twitter cloud service.
