Re: Inconsistent fall survival & jumpers bouncing off

[Gervase Lam]

Just to say that I still working on this.  Honest!

One thing I realised before I started tidying up the PinguMidAirMover was 
that it can apply to any type of object.  So long as the object gets 
affected by gravity, it can use the mover.  So I've renamed it 
GravitationalMover.

Also, I noticed that on each game update, the code uses a constant 
velocity in order to update the position of a falling Pingu.  This is not 
physically accurate, though it is better than it used to be.

This evening, I came up with a very simple solution that is more accurate. 
As it is more accurate, that means it SHOULD be able to solve the problem 
of Pingus dying "inconsistently" from various fall heights.

Unfortunately, I have stuff outside of Pingus that has some deadlines.  So 
give me a week or two.

Thanks,
Gervase.
