This cleans up a bit of code and solves a few edge cases where an item
could be lost, the game be unresponsive, or miss fire an event during
lag cause of the cursor not reflecting the currently held item.
* Move declaration of dItems to items.cpp
This array is never used in dungeon generation, it's closely related to Items so should be kept together. Ideally managing dItems can become responsibility of a container for Items, which will handle adding/removing items from the list and keeping the positions in sync.
* Rename SetPlrHandItem to match purpose/use
* Give more descriptive name to GetPlrHandSeed
This function sets a new seed on a given item struct, not just the held item.
* Don't use HoldItem as a temporary for the players initial inventory
* Take Item by reference in RespawnItem
* Don't use holdItem as a temporary when dropping gold on death
* Update DeadItem to take item by reference, and refer to it consistently
Move code which invalidates the source of dropped items to the caller
Most call sites use a temporary item instance or remove the item from the container, so there's no real point invalidating the item after it's been copied to the drop list.
Update DeadItem to take position instead of player references
Makes `CelSprite` unowned and adds a new `OwnedCelSprite` class for
owned sprites.
This clarifies ownership and makes the code cleaner in a number of
places.
Additionally, because the `CelSprite` class is now tiny (1 less
pointer), we can pass it by-value instead of by-reference, removing a
pointer indirection in the rendering functions.
The other use of dObject is displaying the contents of that array so makes sense to leave as is. We're also able to remove the map since we can reference the current object type value directly on the returned object.
