Colony expedition system

[Thodor12]

Changes proposed in this pull request:

• Expeditions are virtualized events that can be started from a new visitor that will appear at the townhall. You may talk to them and begin preparing for an expedition. You will have to give them a given amount of goods and assign one or more guards to travel alongside them.
• Current and past expeditions can be viewed from the townhall, you will be able to see what you provided them, which guards were sent along, who died (if any), and everything they managed to find.
• The system is highly modifiable through the means of datapacks, from the expedition types to the loot tables.

Currently a draft, mostly looking for initial implementation feedback and feedback on the actual loot tables that come with the initial expeditions.

[ ] Yes I tested this before submitting it. [ ] I also did a multiplayer test.

Review please
