pluggable jars for datasources stores/libraries

[barthanssens]

Using Service Provider Interface for datasources could be useful for allowing users to support their own stores/libraries (e.g. Sesame or a plain-old RDBMS, deprecated as triple store by Jena and Sesame but good enough for some purposes), without having too add all those dependencies to this project.

Hi Bart, I think what you want is already possible as a result of the refactoring that I did over the last weeks. For instance, the refactored code base allows me to develop an extension for a different type of data source (see https://github.com/hartig/BlazegraphBasedTPFServer) without having to duplicate anything from Server.Java
