Art required for user.infratile
#42920 makes client to show a "cursor" sprite in a tile where user is currently placing infra to. That's tag "user.infratile" from the tilesets. As a temporary solution, all tilesets are reusing "user.attention" for this, but it would be good to add distinct graphics for it.
