bigger pydc update: - cleanups and refactoring - python 2 fixes in var conversions (especially w/ respect to int vs long) - fix to pydc.free() which didn't work at all - fix to return python bool as actual bool - test lib covering all conversions (manual verification, though :-/)

# TODO:
#  - how to handle C files? such as intutils.cpp and ldynguess.c
