Feature: Show simulation history arguments

[duranb]

Resolves #1419

To test:

1. Create a banananation plan and navigate into it
2. Add some activities
3. Run a simulation
4. Open the simulation panel
5. Verify that there is now a collapsible Arguments section for each simulation under "Simulation History"
6. Change some arguments for the simulation
7. Run another simulation
8. Expand each Arguments section under the "Simulation History"
9. Verify that the values of the arguments are accurately displayed

Looks good to me, thanks @duranb! Tested locally by sim'ing banananation with lots of different arguments. Just one small question above
