New special nodes:

- Town set attitude for affecting single creature, adapted from Windows code; technically redundant, but maybe handy
- If numeric response
- Print nums (for debugging)
- SDF arithmetic - add, subtract, multiply, divide, exponentiate
- Store random to SDF (adapted from Windows code)
- Display picture (inspired by Windows code, but the implementation is completely different and totally incompatible)
