Updates DecalRoad, MeshRoad and River to be able to write out via persistManager using specialityField functions, similar to ConvexShape

Fixes behavior with gamemode selection in ChooseLevelMenu so if there is only one gamemode, it is auto-selected and advances to the level selection
Update ExampleLevel in ExampleModule to have updated gamemodes field name
