Rationalise Location

[paperboyo]

During discussions, we touched on:

• Remove in chip/alias, make location chip work for all Location sub-fields (like in has)
• Add subLocation chip
• Remove location as an alias for subLocation (here)
• Make +has:location do what it’s supposed to (return images with any location data present)
• Think a bit if four chips: country, city, state, subLocation could not have a better chip UI of offering a secondary sub-choice for a location key (but still allow just typing a value without specifying a subfield). This new chip UI could be reused for other “structured” chips and would simplify/shorten user journeys
• Remember we still do not support new Location schemas (shown and created) (here)
• Spare a Christmas thought on normalising location metadata, providing cleaning, spelling, typeahead and GPS>location parsing (reverse geocoding, like eg. this here)
