Open object format

- To make prototyping and possibly future custom content easier, I've created a JSON-based object format with the same properties found in The Sims
- Renamed dorms directory to dorm
- Added some d20 C code I found to possibly enhance the skill system in the future
- Added voting machine by Don Hopkins
- Removed core.h in favor of niotso.zig which accomplishes the same thing
