Preparation for multiple fluid simulators.

Moved all simulators into a subfolder.
Replaced cWaterSimulator and cLavaSimulator with a generic cFluidSimulator.
Moved original fluid simulation into cClassicFluidSimulator.
Fluid simulator parameters (MaxHeight, Falloff) are read from the world.ini file (can have nether-like lava with lower falloff)
