Vivarium Zoo

New:

- Owners and staff: signs, tills, troughs, info boards and anchors belong to whoever placed them. /vivarium staff add|remove|list manages your staff.

- Care brush: brushed animals stay pleased for a while and raise the welfare of their species. Config: careMinutes, careBonus.
- 20 awards (advancements), from the first enclosure to a world-class zoo.
- Handbook chapters for the care brush and for owners and staff.
- English and German texts.
