Name: load_properties - load the current room properties into the player

Syntax: 
	load_properties()

Description:
	The load_properties call loads the properties from the current envi-
	ronment into the player. This is useful if one or more properties
	change while the player still is in the room or if the player has been
	moved around without using move_player.
	Actually a player should never be moved without using move_player.
	Doing so breaks the combat system.

Return value: none

Examples:
	this_player()->load_properties();
