added funcs for submitting custom remote jobs to rest server

@yarden-livnat this adds support for Robert F to be able to send custom cyclus commands to remote execution so he can retrieve extra data about the cyclus archetypes/agents for scenario creation gui.  I'm not sure exactly what he needs to do to be able to get the CyclusJob instances when they are done, but I presume you can figure it out with him.  I added a getStdout func to the CyclusJob class - that will contain the data that radio needs.  The code has not been tested in any way - no guarantees.
