The preset names should also be localizable string options for the Traffic Sign field.

These presets understandably focus on the generic values, which apply internationally. But we should probably also add presets for each country’s standard warning signs that set traffic_sign to a sign code; otherwise, we might inadvertently nudge mappers to replace the specific values with a generic value that has a nice icon, resulting in dataloss.

I think this is a very real possibility in some regions, such as Central Europe and Scandinavia, where traffic_sign has been mapped to great detail. At the same time, the code-based traffic_sign syntax as documented on the wiki is unsuitable for proper editor support. An alternative syntax is in use regionally that would be much more amenable to software support, but the wiki doesn’t really acknowledge this alternative: #11 (comment).

I'll separate addition of boundary=hazard into its own PR so that #916 can be resolved before this issue is addressed.
