Tracking issue for version 0.4.0 about carrycapacity

Updated the list: We also need to render what's being carried in-hand to the player now when they're in first person mode. Also to prevent hotbar switching I believe we do need a game patch as well.

Tested out a private pre-release with HelDM and crew, found two issues, but they seem to be fixed. I belive the old-version-attribute-updating works now. Also added two new TODOs: Displaying an icon depending on current action in interaction circle and investigating the floating blocks at feet, which likely is some weirdness in the engine.

While I was able to add the hotbar slot locking code, unfortunately my merge request hasn't made its way into 1.8 (at least up until 1.8.3 so far). May have to wait until 1.9 after all.

Additionally another issue came up with animations not being stopped if the server requests so?
