[TRY2]user32: load hook DLL using LoadLibraryExW with altered search path

[Hongbo Ni]

As requested by Dmitry Timoshkov, I have created a standalone test case for
DLL injection via SetWindowHookEx. Here is the zip file containing source 
and exe/dll. http://www.njstar.com/zipfile/hooktest.zip

How to Test:
1. start window/wine's Notepad.exe from GUI or command line
2. run BIN\HookTest.exe, a GUI is shown.
3. goto menu Test - '1. Inject DLLA.dll into Notepad' 

For more details, please see README.txt in the zip file.
