Resolve {@link} links in configuration reference

Currently configuration reference documentation does not resolve

links.

It'd be nice if it'd point to the javadoc of the corresponding class if available!

Examples:

• Fully qualified class name of a class that looks up a reference to a {@link javax.transaction.TransactionManager}

  . The default provided is capable of locating the default TransactionManager in most popular Java EE systems, using a JNDI lookup. (Javadoc)

• Fully qualified name of the class that the configured {@link org.infinispan.marshall.Externalizer} can marshall/unmarshall. Establishing the link between type marshalled and {@link org.infinispan.marshall.Externalizer}

  implementations enables users to provide their own marshalling mechanisms even for classes which they cannot modify or extend. (Javadoc)
