- NtUser/CreateWindowExA/W:
  - During testing I found one application not working with the new mdi support changes.
VIDE from the Vgui C++ project was creating a bugcheck trying to access kernel space. Just
for precautions I moved the kernel code back into user32. After testing the application,
it worked fine. So, I'm reordering the execution of CreateWindowEx. Keeping a small
part in kernel space and the rest in user. This has caused code duplication in user32, but
I want to set this straight first. I will sort out the code duplication later. Sorry for
the mess.
