adapting to new flext lockfree structures

much better detach method handling (one thread for all object instances)
use PyGILState_\*() functionality (enabled with PY_USE_GIL)
ooops, fixing typo
fixing numpy initialization quirks
pyext._init is now called after __init__
enabled use of inofficial PD functionality for search and help path access (#define PY_USE_INOFFICIAL)
added sketch for new pye (Python expression) object
buffer protocol adapted for Python 2.5
