Minor change to look, examine, etc.

The look, examine, and read commands were changed a tiny bit: they'll now
handle position modifiers (such as "inv.") better, or at all in some cases.

When looking at containers, the output will look a tiny bit different as well.

Herbal kits will behave a bit more like regular containers: they will no longer
show their contents when you just "look" at them.

All as of the next reboot. Look out for bugs :)
