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) git-svn-id: http://mc-server.googlecode.com/svn/trunk@956 0a769ca7-a7f5-676a-18bf-c427514a06d6
