Fix Simulator

This "fixes" the simulator by creating a new connection and exchange for
every event to prevent hangups or other weird errors. This is obviously
not a good solution, but it's only a temporary simulator so we'll live.
Some seed data, probably want faker here
Add Faker data generator to simulator
Splitting up the architecture. Broker to Invoca and Broker to Browser have now been separated for code modularity.
Able to run Broker and use the simulator to communicate with the simulated Invoca API
