multiply inlets for py (hot and cold inlets)
small optimizations and fixes use PyGILState_\*() functionality (enabled with PY_USE_GIL) updates for DSP processing __str__ method for pyext, to enable print self calls added message bundle functionality (pyext.Bundle class) enable compiled-only scripts (without .py) enable optimization of Python code in reease build let _inlets and _outlets default to 0 fix for numpy some ASSERTs for explicitly created pyext classes (should be runtime checks i guess) open editor for script under OS X fixing numpy initialization quirks enable symbol binding for all callables (not only functions and methods) _isthreaded is now a data member instead of a method fix for gcc4 added pyext._list and pyext._tuple to convert input lists to Python sequence objects enable module packages (module/__init__.py[co]), now also for Max python-like dotted module.function syntax cleaned up float vs. int pyext tags compiler flag to exclude DSP objects some optimizations and py reload fix more safety for calls where association python-pd has already been removed always run Python interpreter in the background svn path=/trunk/; revision=7474
