Fixing the weather

Fixed by total removal on february 2008.

• Bugs such as disappearing floors
• Too much granularity
  • Could be due to bad elevation values.
• Requires the world to be rectangular without missing maps, which is a problem for pupland.

• Hooks in scripts (like the get_time, script should be able to use get_weather(object/map) to get temperature, humidity, etc). Imagine a powerfull sword that does not work below 5 Celcius :)
• Weather dependent objects
  • Stuff that freezes and melts
    • Could make entrance into some maps interesting
    • Could possibly use same concept for dried out rivers and flaming pits (or something similar)
• Instead of replacing objects, create various states that they may assume (regular, wet, snow, dry, etc)
  • leaves overlays to dms
  • allows for more objects to be affected by the weather
