Rebuild reactor

• Creates designs from old code
• Redesign for usability
• Implement 'Fission Reactor'
• Implement 'Thermal system' (reactor -> heat)
• Implement 'Steam system' (water + heat -> steam)
• Implement 'Reactor Turbine' (steam -> power)

Replace reactor explosion with meltdown. In which the reactor heats up, melts its containment wall, and can flash steam nearby water causing explosions. Doing this will result in more interesting gameplay. As the player may be unable to stop the reactor once it gets beyond a set point. Instead will have to design the reactor with safety in mind. As well countermeasures in case it fails.
