NUI inventory screen

[BenjaminAmos]

Description

This pull request converts the in-game inventory screen to use NUI. It should function almost identically to before, however it may look a bit different. Any UI design critiques would be appreciated also.

Testing

• This pull request affects all screens that use the inventory's functionality.
• The following screens are affected and should be double-checked against an older build to identify possible regressions:
  • TutorialManager
  • BuyItemsScreen
  • SellItemsScreen
  • ChangeShipScreen
  • ChooseMercenaryScreen
  • GiveItemsScreen (give items to a mercenary)
  • HireShipsScreen
  • ShowInventory (the "Items" screen)
  • TakeItems (take items from a mercenary)
• As a guide, at least the following things should be checked:
  • Is the appearence similar to before (or better)?
  • Do all of the key-bindings work as before?
  • Does the screen function the same as before (or better)?

Notes

• This depends on Adapted Main Menu screens to use NUI #631.
• Until Adapted Main Menu screens to use NUI #631 is merged, it might be easier to view the changes made in this pull request by viewing the diff between the two of them at BenjaminAmos/DestinationSol@nui-main-menu...nui-inventory-screen.

I should have mentioned before that MovingBlocks/TeraNUI#66 and MovingBlocks/TeraNUI#67 contain bug fixes that should help with testing this pull request.

[BenjaminAmos]

There is another bug fix for NUI which allows this pull request to render correctly: MovingBlocks/TeraNUI#69.

This was replaced by #668.
