Remove spy/arcfiend only rounds

[Kotlol]

I'll just make a list of things we want for Spiefs:

- Start with Agent Card.
- Maybe one spy tool besides a camera.
- More fun objectives (even if they are suggestions)

What I still want:

- Rewarding Spy's for eliminating other spy's from the board. (taking their rewards)
- Maybe a round that is focussed on Spy vs Spy and normal Spy thieves.
