[docs] Py_SetPythonHome() before Py_Initialize()

Your "Initialization, Finalization, and Threads" document* explains
that embedded Python applications must call Py_Initialize() before any
other Python/C API functions, with a handful of exceptions. It seems
like Py_SetPythonHome() should be among the exceptions, but it isn't.
Initialization potentially relies on "home", so Py_SetPythonHome() is
useful before Py_Initialize(). This situation is similar to
Py_SetProgramName(), which _is_ permitted before Py_Initialize().
Also, in practice, the implementation of Py_SetPythonHome() only
accesses a single static global variable, "default_home". (This is
based on a spot check of 2.0.1, 2.6.7 and 3.2 branches).
Clarification would be much appreciated, since it might help me avoid
a hack. Thanks,
