Fix stupid recursion bug in one SquidPanel method

SquidPanel.animateActor(int, int, boolean, char, Color) was calling
itself infinitely without intending to. This previously caused a
StackOverflowError, and is now fixed to have correct behavior.
ThinWallDemo showed this bug right away, and it has also been updated,
but just to try a different font and correct an offset issue.
