Placing new random Terrains Tiles without moving Mouse Cursor #3381

AsIs: When placing a TerrainSet, I need to move the MouseCursor out of the desired Tile and back in again to place another random Tile of the same type at the same spot, like shown in the GIF animation below.

ToBe: I don't need to move my MouseCursor at all, just clicking on the same spot places another random tile (which fits of course)

// This would be quite helpful to optimize terrain after it has been placed. So when I created a grass landscape I can later improve it by changing here and there some Tiles to other random elements just by clicking on the same spot several times to randomly cycle through different tiles until I like it best.
