- qdel() instead of del()
- z in config.station_levels insted of z == 1
- Typo fix
- Playercount is now 2 instead of 1 which was debug setting
- AI is now properly deleted when struck by very strong explosion (heavy impact).
- Hardware now properly uses install(). Hardware list is generated from existing datums using typesof()
