Implement module-level messaging in module config class and runtime class

[smithed]

In config parent, add field for queue names and create property nodes for setting these queue names
In runtime parent, add field for queue references, add a queue type definition (cluster>>string for now), add property node for getting (not setting) these references. Add function to runtime parent which initializes queues. Other options can be added later.

.....is this still an active issue? Looks like a commit back in 2014 was supposed to close this one.

Note the stream of the commit, its in a branch besides master and therefore doesn't close the issue.

Basically I started implementing is but got distracted. There is a similar branch in the standard engine, I believe

Edit: I think this one is done, and standard engine was close but I maybe didn't test it? Anyway at this point the code would be a beast to merge.
