Subject: Ruby code generator for C++.

Not yet in active use yet but two sample templates are provided.

Note: same dependency story as java codegen: distribution has pre-generated
code so ruby not required to build a distro. Only required for svn working
copy builds.


git-svn-id: https://svn.apache.org/repos/asf/incubator/qpid/trunk/qpid@561468 13f79535-47bb-0310-9956-ffa450edef68
