new base class for py and pyext classes
preset sys.argv for module loading
support for buffer objects (preliminary)
py: bang in left inlet now really triggers without arguments
fixes for detached operation and single-threaded version
little restructuring
adjust pd and py files for correct argument passing
more optimizations
