Feature Request - Game speed indicator

An indication of how much faster the game is actually
running than "real speed" when it's in fast forward... this
could be a percentage of the "real speed", for example.

Also, a quake-like "Turtle" icon appearing in the corner of
the screen if, at any time, the game is running slower
than what you would consider "real speed", i.e. if the
game slows past the point that a normal computer
running at normal speed would show. Useful for
diagnosing network de-sync's if a computer is too slow or
if the game is being run on an old computer.
