Movers and Colliders for Fallers

[Gervase Lam]

Attached are some tidying up of the Bomber and Collider code.  Also 
included is the use of Movers and Colliders in the Faller code.  This 
means I've now fully sorted out the "Bomber stops in mid-air" bug and 
move_with_forces() can be removed!  Though it might be best to keep 
move_with_forces() around for the time being, just in case.

For some reason, I get the message "cvs server: I know nothing about 
<filename>" for the Mover and Collider files I sent previously.  According 
to the CVS mailing list, the base classes were committed but not the 
derived classes.

So, I am also attaching the Movers and Colliders files.  The only changes 
made from the files I sent previously are to "pingu_collider.[ch]xx".

I've tested out the Faller code on drowning, deadly velocity and bouncing 
off walls/ceilings.  Nonetheless, I think it might still be a good idea to 
get the changes code reviewed and test it out.

While testing drowning, I found that Diggers had the cunning ability to 
dig through water.  That's the next thing I'll fix.

Thanks,
Gervase.
