Beta 4 - Tomb of Princes HARD

[RobSeegel]

Verified all fixes - one *minor* issue slipped through:

15696 - Half-stuck: if Jack rides the left-most falling platform down, and jumps to the left, there is a small ledge right at the edge of the screen that he can land on. He is effectively trapped unless he jumps off to his death.

15890 Jack Stuck. Jack can climb down from the ladder in the room above and get to this point (see pic).

Jack had to jump before he got the secret. 'S' should be at walking level.

I finished with only 20 secrets, and Vern said there were 28 in Hard. I wonder if any of the other secrets are not on walking level, they should be checked.
