Add API endpoint for sending Colony thing data
A new endpoint is needed so that colonies can send their thing list once per game load instead of every time they open the console.
The payload will now also include the names of the things in the language that their game is so they can be indexed for the Web UI.
This will also make things faster for checking stock when opening the console since we don't have to convert the list to things each time.
We can set a TTL on how long to cache the colony thing list.
