[osmtools]

please add the taginfo.json to your project. then everybody can see your editor in the taginfo projects and if somebody looks at the parking:lane-keys you can see that your editor supports these keys.

need a short example, then have a look at https://github.com/osmtools/direction/blob/master/taginfo.json
