Support Out-of-Process Remote Server-side API

[vinomaster]

We have received requests to address the need for Clustered and Long-living Process Deployment Models.

The primary objective here is to extend our architecture to allow for a remote Java participant in a session in addition to existing JS participants..

This task builds on the design changes described in Issue #147.

We have discussed an approach that will cover the following capabilities:

Class: Collab

• Java and JavaScript implementations of API is required.

We have the moderator model in place. This issue will address the need for a remote server side entity to connect to a cowed session.

One scenario may be some sort of EJB that is bound to a particular session. One could start the EJB, the EJB could join the session / start the session before any JS participants join.

We need to implement the following.

1. Need a Java api that mirrors our prep and collab api's
2. Tie the op engine code into the api.
