search command

[Peter Mardahl <peterm@soda.berkeley.edu>]

I'm going to take over the 'search' command.  Right now,
it's use is solely in shops, I think.  this is made mostly
obsolete by the shop listings.  Also, it's buggy code,
I hear.

At any rate, the command name is moving from 'search'
to 'search-items',
and the function name which uses it is changing from
command_search to command_search_items.

The new search command I'll be installing is intended to
find hidden things and traps such as runes.
