python-like dotted module.function syntax
reworked outbound message generation (now with symbols instead of one-element anythings)
multiply inlets for py (hot and cold inlets)
cleaned up float vs. int pyext tags
pymeth object for object methods
enable built-in functions
sequence protocol for symbol type
enabled built-in functions
py: allow all callables
