Feature suggestion: Make footstep sounds dependend of terrain type

[Schegbouwer]

Being able to hear footsteps that correspond to the snowy Solstheim, the wet Bitter Coast Region, or a dry Ashland would surely give an extra dimension to exploring Morrowind, I think.

Most probably mods can achieve this feature. We also probably need a new function that returns the terrain type/terrain ID or something...
