when geocoding fails, provide alternate way to add lat/long to event locations

[michaelglass]

related: #668

right now, we try to automatically geocode addresses, but when that geocoding fails, there's no interface for manually setting lat/long.

I recently went through and manually set location information on about 15 locations, but that's not the best / sustainable solution

This seems like a great issue for anyone to dive in and suggest where to put this UI -- would be great to have input from new and experienced users of Bridge Troll!

@michaelglass is it possible to update the latitude and longitude for the location called SignalAI in the UK, the map on the event page is very misleading.

The correct location values according to Google maps are
51°31'38.4"N 0°05'17.6"W
51.527325, -0.088209

The location is:

We have just published a new ClojureBridge London event and the map on the page is a long way from the actual venue.

Alternatively, is it possible to remove the Google map image from the page?

@jr0cket done. AFAIK I don't think there's an option to hide the map.
