Outdated Drools 5.3.0.Final documentation

Originally reported to BZ. Geoffrey, I wasn't sure who to assign this to, I hope you don't mind I gave it to you to reassign as appropriate.

Copied from BZ:

Description of problem:
Documentation for Drools 5.3.0.Final is outdated because in part Drools Expert,
section 8.6.4. The Audit View, is used outdated example about creating audit
log where deprecated RuleBase is used instead of KnowledgeBase.

Link to this documentation:
http://docs.jboss.org/drools/release/5.3.0.Final/drools-expert-docs/html/ch08.html#d0e8131

Version-Release number of selected component (if applicable):
Drools 5.3.0.Final Documentation

Actual results:
WorkingMemory workingMemory = ruleBase.newWorkingMemory();

// Create a new Working Memory Logger, that logs to file.
WorkingMemoryFileLogger logger = new WorkingMemoryFileLogger(workingMemory);

// An event.log file is created in the subdirectory log (which must exist)
// of the working directory.
logger.setFileName( "log/event" );

workingMemory.assertObject(...);
workingMemory.fireAllRules();

// stop logging
logger.writeToDisk();

Expected results:
...something like this...
KnowledgeBase kbase = readKnowledgeBase();
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
KnowledgeRuntimeLogger logger =
KnowledgeRuntimeLoggerFactory.newFileLogger(ksession, "test");

ksession.insert(...);
ksession.fireAllRules();
logger.close();
