Auto-registration of Query interceptor, dynamic Search engine reconfiguration

We need the Lifecycle of the module to be coupled to the cache, use the new Hibernate Search feature to "dynamically" reconfigure itself based on new types which might be encountered during a cache event.
This also removes the need for a QueryHelper, and makes sure the configuration properties are not passed at runtime but are written in the Infinispan configuration file.

Includes an update to Hibernate Search 3.4.0.CR1
