tome2-ah: instant pseudo-ID only works with automatic item pickup

[Therem Harth]

Picking up items manually doesn't seem to do the trick, with the exception of potions. Not sure why; object_pickup() calls sense_inventory() every time, so I guess picking things up manually doesn't call object_pickup()? Maybe the item pickup code is duplicated for manual pickup.

[Edit: this is in the C/Jansson version. Not sure about the C++ port.]

I would recommend auto-pickup anyway so as to avoid missing good items, but T2 has a ridiculous number of junk items for any given class.

BTW, instant pseudo-ID is cool and all, but it does kind of relegate cursed items to the status of background flavor. I should come up with some mixed blessing items for T2, so that cursed status is more ambiguous.
