* Source/win32/WIN32Server.m:
* Source/win32/w32_movesize.m:
Fix a rather serious error where the extra window data was allocated
in two places (allocated with objc_malloc in the WM_CREATE handler,
and also allocated by Windows using the cbWndExtra field of the window
class structure). Sometimes the window level was accessed from one
memory area and sometimes from the other.
	
This is a quick fix that leaves the level and ordered properties
in the cbWndExtra area, and the rest is left in the WIN_INTERN
structure. 

This fixes the problem where window ordering was broken when running
apps in gdb.
