Create note and add comment as anonymous

[ThomasG77]

To create note, there is an http call to createNoteRequest. In this function, the call to endpoint is using auth.xhr related to "osm-auth library". With it, you can create note when authenticated but you can't as an anonymous contributor whereas the OSM API endpoint allows this function.

You can also comment note as an anonymous contributor. For the same reason, the usage of auth.xhr in genericPostNoteRequest (function use for http call to comment note), it's not possible to comment anonymously.
