baldurk 9db71b803a Change python wrapping of arrays to be more pythonic, by reference
* Previously we would convert from python to C++ arrays immediately by
  copying, and vice-versa convert TO python immediately by creating a
  new python list by copying.
* This however behaves rather poorly in common situations, e.g.:
  > foo.bar.append(5)
  Would not append 5 to foo.bar, but copy foo.bar to a temporary, append
  5 to it, then destroy it leaving foo.bar untouched.
* Instead we leave the C++ array type as a pointer for as long as we can
  and instead implement the python sequence API as extensions/slots that
  work in-place on the original array.
