API Upgrades

[docuracy]

Manuel Claeys Bouuaert / Allmaps has requested:

• - 'similar to' API search
• - geometry type/existence filtering
• - returning JSON on API errors

Also noted that of these URLs, the second tends to fail:

• https://whgazetteer.org/api/index/?name=Londo
• https://whgazetteer.org/api/index/?name=London

Elton Barker says:

"Having chosen WHG as my gazetteer, I now get multiple options for the place information in the document I'm annotating. Of course, this is no surprise, given the multiple records WHG has. However, as a user of RS, I'd want a little bit more information about the different WHG records for a place, in order to choose the one most appropriate "gazetteer" for the document that I'm working on."
