#53 - Set up Slf4j logging and excluded Commons Logging.
#50 - Added @EnableHypermediaSupport annotation.

The annotation registers supporting application components as Spring beans based on the configured hypermedia type. Currently supported are the default rendering as well as HAL. We register a matching LinkDiscoverer implementation as well as the appropriate Jackson modules (if present on the classpath) to support HAL.

Upgraded to Spring 3.1.4 to benefit from fix to prevent multiple invocations of ImportBeanDefinitionRegistrars (see SPR-9939 / SPR-9925).
