Minor improvements to Rakefile and added profiling data anlalyzing tasks.
Improved profiling modes of interactive client.
Enabled logging, even if server is run with -O
Extended chunking benchmark.
Sped up profiler by aggregating messages in memory and lazy serializing.
Added cProfile lines to run-server - they are commented out and only there for easy access (don't want to add yet another run mode, till the mode (and parameter!) managment is easier)
New pipeline concept! Time wise everything is more serial, data wise it's more parallel. Every pipeline.Element is processing a stack of messages at a time.
Adjusted ProfileParser to new reality.
Sped up test output printing through rake.
