annotate python/pythonServer.py @ 2376:c41caaa96633

Some fixes for #90. Also a failsafe loop if the server never responds with meaningul information from saves (for instance, running only on apache or basic http servers). More changes to pythonServer for python 3.5. Please check if still valid on 2.7
