Lua mode fixes (#1087)

- Lua config is now applied to w3i even if no buildMapData is present
- Player config gets correctly injected into the script in lua mode
- Use // floor division operator for translating integer division
- Use math.tointeger to ensure correct representation of integers, aligning them with Jass
- Standard library has been adjusted to not rely on integer underflow wrapping
