* Added TranslateMessage call to SDL default message pump - was causing problems in S2 tools mode apps that used Qt. Qt relies on the WM_CHAR message generated by TranslateMessage and keyboard input was showing up in the UI as mixed-case. (Depending on which message pump got a given message - both SDL and Qt pump messages for the entire process.) Sam will review and possibly tweak this change before propagating to public SDL, but I'm checking this version in so I can integrate into S2 and fix the issue there.
