Dangers and obstacles

[Noitarud]

Describe the idea

I don't want to call these favourites but seems to be the way to add them. Application needs images with typical danger sign themes (lasers, radioactive, smoke) the public may see, maybe include nautical themes too. Needs #11605

maybe allow a do not rout near option, and warning when the rout or destination is going near one. specify warning radius so you don't forgetfully go near it. This might combine with #7669.

Expected behaviour

When avoiding, specify a length or radius

Alternatives you've considered

7669 but needs descriptive emblems

yes I got the idea, similar to road shields where you could put text in frame. Well something to think of in the future
