Subject: * Revert 'Handle dead keys more gracefully by taking a "best guess"
 rather than   ignoring completely' from r1459; it can't ever work acceptably,
 especially on   azerty/qwertz layouts * Make the ordering of the output from
 in_keyboardDebug more sensible * Add cl_consoleKeys cvar, a space delimited
 list of key names or characters   that toggle the console
