set correct default ports for transport connectors stomp and openwire

The defaults per Apache's docs specify these as the default ports:

[Stomp](http://activemq.apache.org/stomp.html ): 61613
[openwire](http://activemq.apache.org/configuring-transports.html): 61616


However, in the activemq.xml templates, stomp=6163 and openwire=6166.  Must have been a typo originally? 

This caused a few headaches when using the [puppetlabs mcollective module](https://forge.puppetlabs.com/puppetlabs/mcollective) to configure mcollective.  I know you prefer not to have  mcollective-specific configs, but these are the true defaults per Apache.  Thanks all!
