void fix_generated_item	(	object *	op,

fix_generated_item(): This is called after an item is generated, in order to set it up right. This produced magical bonuses, puts spells into scrolls/books/wands, makes it unidentified, hides the value, etc.

4/28/96 added creator object from which op may now inherit properties based on op->type. Right now, which stuff the creator passes on is object type dependant. I know this is a spagetti manuever, but is there a cleaner way to do this? b.t.

Parameters

op	object to fix.
creator	for who op was created. Can be NULL.
difficulty	difficulty level.
max_magic	maximum magic for the item.
flags	GT_ENVIRONMENT: if not set, calls fix_flesh_item(). GT_STARTEQUIP: Sets ::FLAG_STARTEQIUP on item if appropriate, or clears the item's value. GT_MINIMAL: Does minimal processing on the object - just enough to make it a working object - don't change magic, value, etc, but set it material type as appropriate, for objects that need spell objects, set those, etc

static void free_artifact ( artifact * at )

static

Totally frees an artifact, its next items, and such.

Parameters

at	artifact to free. Pointer is free()d too, so becomes invalid.

Note: Objects at->item are malloc()ed by init_artifacts(), so can simply be free()d.

But artifact inventory is a 'real' object, that may be created for 'old' objects. So should be destroyed through free_object(). Note that it isn't on the usual item list, so some tweaking is required.

Randomly adds one magical ability to the given object.

Changes the item's value.
