[KERNEL32]

Implement client-side only of console font APIs: - documented: GetConsoleFontSize, GetCurrentConsoleFont; - undocumented: GetConsoleFontInfo, GetNumberOfConsoleFonts, SetConsoleFont (see http://cboard.cprogramming.com/windows-programming/102187-console-font-size.html for a working usage example of these APIs).
