AMQP-295 Fix Version in QuickStart

The <version/> element in the maven dependency
stanza in the quick start was obsolete.

Use newer version of gradle docbook plugin that
now supports replacing the ${version} placeholder
in files other than index.xml.

Update build.gradle to add the quick start chapter
to the 'expandPlaceholders' property.

Change quick start chapter to use the ${version}
placeholder.

AMQP-281 Shut Down Timer in AMQP Appender

When using the AMQP log4j appender, it
can cause orphaned daemon threads when undeploying WARs.

Also, when exiting main() methods, apps should call
Log4jConfigurer.shutdownLogging(); in a finally block
to destroy() the connetion factory (releasing threads
used by the rabbit client).

AMQP-282 Log4j Appender - Configurable Charset

A charset is used when converting the message body
String to a byte[] to send to AMQP.

For backwards compatibility, the appender uses the
system charset by default, but now allows the charset
name to be specified in the log4j configuration...

log4j.appender.amqp.charset=UTF-8
