[REL]Bad weather fix for SH3

[Hitman]

My idea (inspired from Hitman) works in the debugger. I found the location where FogChangeSpeed is stored. By setting this value to 0 no fog can arise. So it's possible now (in principle) to directly affect fog - without using the indirect way by changing windspeed. So one could reduce fog occurence arbitrarily (using random numbers or counters).

As you already rightfully stated, the first thing to do is just to fix the weather, i.e. prevent it from sticking in persistent 15 m/s winds. While actually making an improved weather mod is a second stage, that might come or not at a different time in the future.

But if you find the variables for fog, rain, wind, cloudy skies, etc while you do the first stage fix, then we will already have the foundation of a future weather mod. An added algorythm could relate the wind, rain, fog and cloudy skies, and provide a more realistic climate
