Revamped DXL Server: Introduced Handshake to avoid lockups, allowed specific Port, included DriveDOORS.inc

- For interactive Testing the runServer.bat was replaced by runDOORS.bat which starts DriveDOORS with the right include paths
  and a startInteractive.bat was added
- The Handshake was necessary, because I experienced connection drops after connections through the Python API
Added first version for Implementers Guide

Still not sure if the network protocol should have the scripts send the amount of data they want to send and how to handle the sending of binary data to the DXL server.
