# Description
Defines a new item type with the specified name and model. Item types are the
fundamental pieces of data that give items specific characteristics. At least
one item definition must exist or CreateItem will have no data to use.

# Parameters
- name: The name of the item, that will be displayed on item labels.
- uname: The unique name of the item to identify the item type via string.
- model: The GTA:SA model id to use when the item is visible in the game world.
- size: An arbitrary size value (has no effect in this module).
- rotx, roty, rotz: The default rotation the item object will have when dropped.
- modelz: Z offset from the item world position to create item model.
- attx, atty, attz, attrx, attry, attrz: Player holding attachment coordinates.
- usecarryanim: When true, player will use a two-handed carry animation.
- colour: Item model texture colour.
- boneid: The attachment bone to use, by default this is the right hand (6).
- longpickup: When true, requires long press to pick up, tap results in using.
- buttonz: Z offset from the item world position to create item button.
- maxhitpoints: maximum and default hitpoints for items of this type.
- price: The price of the item, can be used for shop systems.

# Returns
Item Type ID handle of the newly defined item type. INVALID_ITEM_TYPE If the
item type definition index is full and no more item types can be defined.

- x, y, z: The position to create the object and button of the item.
- rx, ry, rz: The rotation value of the object, overrides item type data.
- world: The virtual world in which the object, button and label will appear.
- interior: Interior world, same as above but for interior worlds.
- label: True to show a label with the item name at the item.
- applyrotoffsets: False to make rx, ry, rz rotation values absolute.
- virtual: When true, the item doesn't have an in-world existence.
- uuid: Allows specific UUID to be set instead of generating one.
- hitpoints: -1 by default, if -1 then item type maxhitpoints value is used.
