STD/OBJECT PROPERTIES:
----------------------

Full details of the effects of std/object's properties are below. In
inherited objects the properties may cause other effects (eg BROKEN
weapons have 1/5 weapon class)


BLESSED:
	This is a flag to indicate that the item is blessed. If set
    then short() will be appended with " (blessed)".
	query_magic() will return true if set. 

BREAK,< optional msg >, <minimum strength needed>
	This property indicates that the object can be broken. 
    An add_action to the function break_object is enabled. To break the object
    the player must have strength greater than the integer in argument 2.
 
BROKEN, <msg appended to short_desc>
	If an object is broken then short() will be appended by " (broken)" 
    unless the optional message is set, in which case " ("+msg+")" will be 
    appended. 
	When an object is broken:
	 - it looses all MAGIC, ENCHANTED, BLESSED properties
	 - if the object is a CONTAINER the function spill_contents is called
	 - if the object is a lit light, it is extinguished.
	 - if the object CAN_OPEN it becomes OPEN
 	 - if the item is a light , it runs out of fuel.  
	While an object is broken:
	 - It cannot be opened or closed
	 - spill_contents() is called if the object is a container and picked
		up
	 - It cannot be lit
	 - long() will be appended by "It looks broken.\n"
 	 - nothing can be put in broken containers.
 
CAN_OPEN
	This property enables the object to be opened and closed, like
    a container or book. long() is appended with a description of the open
    state.
	
CONTAINER, 0 , max amount can hold.
	This property indicates that the object behaves like a container,
    with integer argument 2 the maximum weight it can contain.
	Argument one is not used.

DECAY ,<optional ob:func. | message>, <time to decay>
        When this property is set, a call_out to the function decay() in
    the object is set. In std/object decay simply checks if argument one 
    refers to an ob:func cal, if it does call it passing this_object() as 
    the only argument otherwise destruct the object. If an object gets 
    saved in a .o file, a DECAY_TIMESTAMP is set to the current time(), 
    and the time remaining to the decay() call_out stored. When the object 
    is reloaded, if the time left is less than the new time() minus timestamp 
    decay() is called, otherwise a new call out is set.

DECAY_TIMESTAMP, <time>, 0
        Store used by the DECAY code when objects are saved.

ENCHANTED
	This flag indicates the object is enchanted, and short() will be 
    appended by " (enchanted)".
	query_magic() will return true.
 	
HIDDEN
	If this property flag is set, the object has no short(), long(),
    it cannot be dropped or gotten, and no add_actions will work, ie. the 
    object is invisible to the player.
	NOTE: the object will still respond to id()

LIGHT, <>, lit
	If an object has this property, it can behave like a fuel burning
    light. Argument two is the current lit state, while argument one is an 
    array of light variables :
	({ int fuel, string lit_desc, string unlit_desc, string wet_msg })
	If an object is lit, short() is appended by " (lit)".
	If an object has 0 fuel, short() is appended by " (burnt out)".

LOCKED			>>> Not yet implemented <<<
	Used in conjunction with CAN_OPEN. If an object has the status
    locked, it cannot be opened or closed. The BROKEN property negates this.

MAGIC
	This is a flag to indicate the object is a magical Item.
	query_magic() will return true.
 
NO_DROP, <fail msg | ob:func>
	If the object has this property, it cannot be dropped if the object
    and function call refered to returns 1. if arg 1 isn't refering to an 
    object and function, then it is assumed it is a message and it is printed 
    when the object is attempted to be dropped.

NO_GET, <fail msg | ob:func>
	As for NO_DROP, except the return value to block the get is 0.

NO_SAVE 
	If this flag is set query_no_external_save() returns 1.
        note: this will not stop auto_loading objects.

NO_STEAL
	If the object has this property, it cannot be stolen.

OPEN
	This flag refers to the object is open. short() will be appended by
    " (open)".

PREVENT_INSERT, <msg>
	This property prevents the insert of the object into a container,
    printing the message if it exists.

READ, < msg >, <optional minimum intelligence needed >
	This property indicates that a message is on the item and can be read
    by the player. An add_action is enabled to this effect.

SEARCH
	Indicates the item can be searched for hidden items.

SKIRT
	Flag used by /obj/armour. Skirts are armour covering the legs, but not
    enclosing the legs individually. 
 
WATERPROOF
	This property indicates that the item is waterproof, hence
    lights will work while wet (and under water!)

WEAR
	This marks the property as wearable. It automatically add_actions
    'wear' and 'remove'. the string '(worn)' is appended to the short.
 
WORN, <object wearer>
	This flag indicates that the object is worn by the environment 
    (ie. the player - the object is carried). short() will be appended by 
    " (worn)".
	The WORN property is removed if the object is dropped. 
	WORN prevents insert of the object.
