Putting out fires

The latest build should provide some much needed stability for both Windows and Linux users.

I had to re-engineer some of how the simulation happens, so it's not all optimized yet but hopefully you should not see any more in-game crashes!

Some of the minor things are:

• A new 4th tutorial about the cycle of life

• An expensive new tornado that kills trees level 3 and above (Rips 'em right out)

• A new fire simulation that should only burn down your forest - not your computer.

• The sunlight simulation draft is in - Plants grow faster when they have direct sunlight

What's still coming up:

• I need to re-visit some performance stuff that was re-engineered with the old, crashing code

• I'll be re-balancing some of the fire attributes to better simulate brush fires that would leave older, larger trees standing just fine.

• Getting to work on more plant and animal species
