Regenerate road segments when material updated

[TheDuckCow]

If the user assigns a new material to the RoadNetwork, it should add an updated material. Right now, the user would have to trigger a full reload of segments manually (most easily right now by toggling the auto refresh button on and off).

Ideally, it can do this in a lightweight way - iterating through existing meshes and updating their material slot, vs completely regenerating geometry.

Please describe steps to recreate problem. I changed the road texture several times and it always updated instantly.

Steps that I followed:

• Duplicate road_texture.png, invert colors, and rename new image to "road_texture_inverted.png"
• Select RoadNetwork in Scene dock
• Select "Material Resource" in Inspector dock
• Expand "Albedo" to expose "Texture"
• Drag/Drop road_texture_inverted.png or road_texture.png from FileSystem dock into "Texture" slot in Inspector dock
• Outcome: New image is displayed on all Segments in 3D View

Also tried:

• Duplicate road_texture.material and rename to road_texture2.material
• Change albedo texture to road_texture_inverted.png in new material
• Select RoadNetwork in Scene dock
• Drag/Drop road_texture.material or road_texture2.material from FileSystem dock into "Material Resource" slot in Inspector dock
• Outcome: New material is displayed on all Segments in 3D View

Hm, I've retried this myself now and can no longer replicate it. It must have been resolved with some of the other updates we made around how and when refreshing works. I checked out version 0.2.0 for comparison, it was definitely an issue still then, and now is not. Even if I drag and drop a new material onto the network slot now, it immediately updates the road. Closing this issue, apologies for that!
