Middleware: some updates on the MOOS part

I made some changes in order to communicate between MORSE and MOOS through different MOOS communities. I needed to specify different hosts and ports. The frequency of the corresponding MOOSApp is also configurable.
Those modifications are working with my fork from davidhodo/pymoos. A pull request has been sent to his repository.
Now, MOOS is also working with some sensors and actuators (Pose, Light, Teleport).
Other contributions may follow. Thanks for your work!
