- Fixed GetFullPathNameA and debug message in GetFullPathNameW. The path handling is still wrong in some cases, I am trying to find out why.

- Very basic implementaion of NtUserPaintDesktop.
- Fixed bug in default window WM_ERASEBKGND.
- Fixed bug in default window WM_PAINT.
- Made BeginDeferWindowPos, DeferWindowPos, EndDeferWindowPos pseudo-working by returning values that make sense and calling SetWindowPos.
