-Implemented ReadConsoleOutputCharacterA and CsrReadConsoleOutputChar
-Added null pointer check to FillConsoleOutputCharacterA -Added parameter names and removed 'undocumented' label for GetConsoleFontSize and GetCurrentConsoleFont -Added definition of CONSOLE_FONT_INFO struct -Added call to SetLastError(ERROR_OUTOFMEMORY) to a number of RtlAllocateHeap return value checks Patch by Marty Dill svn path=/trunk/; revision=3375
