Summary: win32gui.EnumChildWindows() crashes when no children

Initial Comment:
When the method win32gui.EnumChildWindows(hwnd,
callback, extra) finds the window for which to return
children but the window doesn't have any children it
crashes with the error: "pywintypes.error: (0,
'EnumChildWindows', 'No error message is available')". 

The correct behavior should be to return a empty list. 

However as Mark has pointed out on python-win32 mail
list this may be an unsafe change for already written
code expecting an exception if a empty list is returned
instead. In which case, at least an exception with a
error description should be thrown.
