objstat: Item and monster generation statistics

The -objstat command-line option will generate iterations of the given
levels, compiling stats on every item and monster generated, and
average the results over the iterations. It's only available in debug
builds and uses the same map specification format as -mapstat. The
default number of iterations is 100.
