Alternative geocoding service

[jayvdb]

The stargazers plugin now supports a map visualisation which looks really good. However I would rather not set up a Google Billing account for it.

I think it would be useful to add support for alternative services, especially OpenStreetMap Nominatim which has lots of providers some with reasonable free daily limits, including MapQuest which has a free limit of 15,000 per month. The base url endpoint could be a setting so that the user can choose which provider works best for them. Most JS Nominatim clients support this.

Yeah, without prepaid/virtual cards, setting a Google billing account could be kind of dangerous x)

I'll check the alternatives you provided when I have some free time, or if someone else is interested to look into it 👍
