Add some hashtag to edits coming from QwantMaps

[jonsger]

I think it would be nice to auto add some hashtags to changesets coming from QwantMaps.

In order to do this we could append hashtags to the editUrl and ID will add those hashtags to the changeset, when uploading.

According to the ID API documentation something like adding &hashtags=QwantMaps to the editUrl should do the job. Though I didn't get it working when manually entering such a link.
