  My thought is that perhaps it should go away, but there be some sort of 
compatibility mode, such that if you select some value with old pickup mode, it 
means it is effectively this with new pickup.

  I know that I'm still in the habit of going to 'pickup 4' to pick up 
everything in a dungeon, and then 'pickup 0' when I'm done (4=everything, 
0=nothing).

  I don't really care how that works internally, but I'd be nice to keep those 
old (simple) pickup modes for those of us that do use the command to switch 
pickup modes.

  I would think that those could be converted to new pickup modes in most cases, 
or even pretty close cases (I wouldn't care if pickup 4 actually did skip cursed 
or unpaid objects for example).  Likewise, the value density modes could perhaps 
get rounded/adjusted to the nearest value in new pickup mode, etc.
