Refactoring of Business Tier

[Villemos]

Guys,

A quick update; Following Mark and Johannes refactoring of the
Transport Tier I have been refactoring the business tier and partly
the exchange tier. Its almost done now. The modulization is much
clearer;

- In the exchange tier there is a module per 'service' defining the
messages in/out.
- In the business tier there is the modules implementing the service
(some in different ways).

Functionality is as before, but much simpler structured.

In addition I have create a 'configuration' service. The service
removes the need for the complex Spring DSL files for assembly of the
system. The configurator will build the routes dynamically using the
Java DSL based on much simpler specifications of the parameters/limits/
commands.
