[posila] water-mud is missing tile transitions

[Illiander42]

The water-mud tile is missing tile transitions with:

Sand 1, Red desert 1, Red desert 2, and most of Sand 2 and Sand 3. (These are the localised names in English, since I could get those easily from editor mode)

They should be the same transitions as for all the other water tiles.

Thanks for the report
Fixed for 1.1.0
