Name: query_day - get day information from a room

Syntax:
	#include <room2.h>
	int query_day()

Description:
	The query_day call returns the day condition, set by the weather
	object, from a room. This information is also directly available
	from the weather object, but normally it is faster to query it from
	the room you are in.

Return value:
	1 if it is day, 0 if it is night

Examples:
	int day;
	day=query_day();
