Summary: pywintypes must be explicitly imported before win32api

Initial Comment:
Hi,

I just want to raise awareness of this bug that affects Twisted on Windows using a 'portable' Python installation.
http://twistedmatrix.com/trac/ticket/3868

it looks like the following import will fail

from win32api import OpenProcess
import pywintypes

while changing the import order fixed the problem.

from win32api import OpenProcess
import pywintypes

----

This only happend if I call python.exe from another working folder as the one hosting the python.exe file.
All DLLs are in the same folder as python.exe

I am thinking that win32api is only trying to load the dlls from the current working folder, not the one hosting the python.exe.

Message:
I think we will find that the magic done in pywintypes.py to locate and
load the pywintypesxx.dll module is what fixes the problem in most cases -
without that import I expect it is that DLL which can't be located when
importing win32api.  I'm not sure what a fix is though.
