User32: Added LockWorkStation, ExitWindowsEx, AdjustWindowRect[Ex], and Get/SetWindowPlacement

WinUser: Added ExitWindows codes, Window Style codes, and the
WindowPlacement structure.
In order to use ignore we would need to use JUnit 4's style; instead of TestCase subclasses with testXXXX() methods, classes that are standalone and whose methods use @Test annotations. Is it okay to convert this, then?
