Update to 5.8.0 of ActiveMQ via bug
https://bugs.eclipse.org/bugs/show_bug.cgi?id=410237.  Also removed
reference to javax.jms library inside of org.eclipse.ecf.provider.jms,
in favor of Import-Package and using Orbit-provided access to jms 1.1
api.  Also added javax.jms plugin to feature, so that it will appear in
build.
