Extracts config files from OpenGammaSshDriver

* Adds CONFIG_FILES_TO_COPY, CONFIG_FILES_TO_TEMPLATE_AND_COPY, EXTRA_SCRIPTS and SERVER_START_SCRIPT config keys to OpenGammaServer interface. 
* Mentions of each are removed from OpenGammaSshDriver
* SimulatedExamplesServer class is added to provide values necessary for deployment of examples-simulated distribution.

Important note: Although the branch is called examples-bloomberg, I haven't added the necessary configuration to support that distribution yet! To do so would require: 
* The addition of appropriate config and properties files
* The addition of another class like SimulatedExamplesServer to provide a simple means for deployment.
