standing on gravel no longer causes slowdown as if standing on sand. new config option for gravel

Players are no longer affected by the "terrainSlowdownOnSand" value when walking on gravel. There is a new config option for changing the slowdown caused by walking on gravel. The default slowdown for gravel is 0.

Surface gravel is very rare in the game, but the most notable place you will find surface gravel is in villages where it is used as the road surface. It doesn't really make sense for the villagers to have built roads from something that is terrible to walk on. And I kind of suspect that gravel slowing down the player was not really intended behavior in the first place.

P.S. I'm new at this. Please let me know if I'm doing it wrong.
