(1) Load testing (via JMeter) and related bug fixes.
(2) BUG Fix: AbstractInfoNodeService used a non-final data-member, which caused exceptions during multiple concurrent requests.
(3) BUG Fix: SimpleRssFeedService assumed non-concurrent updates. Concurrent requests were okay, but if a feed needed to be updated, multiple requests would cause multiple connections to be used to update the feed.
(4) BUG Fix: SimpleRssFeedService didn't use the HttpURLConnection configured with connection and read time-outs.
(5) Enhanced XmlPanelSetBuilder, to build panels concurrently, using the ExecutorService. This allows RSS feed panel builders to connect to and refresh from multiple RSS feeds concurrently.
(6) Enhanced XmlCarouselPanelSetBuilder, to build all panels at once, to leverage off of the concurrency now provided by XmlPanelSetBuilder.
