Inventory (Backpack): Have pagination

[JaXt0r]

Description

Inventories in Gothic are infinite. We therefore need to find a way to implement such a behaviour for our VR inventory. Let's go on with a pagination like in Walking Dead: S&S.

Tasks

• Add a paginate left + right button at the bottom of the back pack
• Add a label with calculation of page amounts. e.g 1/3 (first page of three)
