[Windows] More tidyup and robustness for metro app support - debug cleanup and serialization of input (not quite finished) [windows] Refactor serialized input code when used with key event thread model [windows] Add consistent precompiled headers for other projects [windows] Merge console window test into metro support [Windows] Tidy up work and identify additional TODOs for metro-style app support [Windows] Ensure error case falls through to default hook processing for console windows [Windows] Refactor shared memory into memory mapped file so we can cross 32-64 bit boundary [Windows] Tweaks to C++ security calls and parameters [Windows] Start refactor of SerialKeyEvent* classes [Windows] Rename to SerialKeyEventServer (refactoring) [Windows] Complete refactoring of SerialKeyEventClient class [Windows] Further encapsulation and cleanup with 'interfaces' to reduce header pollution [Windows] Complete serialization fix with move of modifier state management from client thread to server thread to guarantee consistency [Windows] Replace atom-based keyboard switching with memory mapped file indexed to avoid security constraints [Windows] Fixup Left Alt+Shift interaction with serializer [Windows] Use Windows 8.1 SDK for test
