* Seperate out socket engines into derived classes of SocketEngine.

* Add a classfactory SocketEngineFactory to create a new socketengine of the configured type
* Implement configure hax to compile only the required socketengine and the base class
* Eliminates ugly defines, and is more in line with C++ ways
