Feature request name
a ZenMethod to set item in player's inventory and hotbar.

Feature request description
IPlayer.setInventoryStack(item, index) and IPlayer.setHotbarStack(item, index) to set item at given index within player's inventory/hotbar, like /replaceitem command in vanilla.

Feature request reason
I want to use a item to consume other items and do something.

Feature request dependencies
It's just like a vanilla command, so don't need any other things.

unfortunately this won't be a thing in 1.12, it is too late in the 1.12 lifecycle to add something like this, as the next release of the mod for 1.12 I am hoping is the last for 1.12, so I don't want to add new methods that I won't be able to provide support for.
