Implements working(!) correlate_resets method

VnumSection has a key? method that just defers to its @entries hash in
order to lookup room/mob/object by vnum. Resets similarly has an each,
<< and [] method that defers to its underlying array, so that
Area#resets can return the resets area itself rather than the hash.

Also fixes some bugs in Parsable and Objects.
