Bugfix/sword in hand

[JaXt0r]

To test

1. Spawn Buddler (554) and Guard (204)
2. Check if Buddler eats apple, cheese, bread, and it is in his hands
3. Check if Guard is doing his sword animation with the weapon in his hands

Hints:

• If you look very very closely, you will see, that the item holding position is a few millimeters off. I checked it with G1. This is normal behaviour.
• Sometimes the world mesh doesn't load fully and NPCs fall down. I created a separate issue for that. Just restart the game if it's happening.

There's a bug remaining. Please wait with review until fixed.

Buddler (535) and Buddler (554)

Ok from my side.
The NPCs from the testplan are ok.

I found 2 bugs while testing, but they don't keep us from merging.
Bug tickets #346 #345 are related and should be solved close to the PR.
