[Feature Request] add a feature allow Inventory grid remember its selection at last close moment when we open it.

[Justus]

- if a grid panel has one slot been selected and be closed, it will remember it and select the same slot when we open it next time
- if there are no selected slot when we close a inventory grid, it will also be opened with no selection next time.
- if we both has Inventory and EquipmentView(or other slot view), we need a method let them behaviors as in a same panel ( or we already has this feature? how to setup them in the scene tree?)

Example:
- case1: (3,2) seleted in inventory, NONE selected in Equipment View, so next time we open them, only (3,2) in inventory is selected


- case 2: NONE selected in Inventory, (3,1) selected in EquipmentView, so next time when we open them, only EquipmentView has selection.

That is up to you. You'll need to find a way jump from one to the other whether it is through navigation or using an input for selecting the panel you want to use.
