Idea: Colour the pins to highlight QA issues

[RobJN]

Make the pins a different colour (e.g. red) if there's an error / problem with the address. [from @rjw62]

I think this is too big a change for me to personally work out how to do (I'm not a proper web developer). Also what would you show? One easier thing to show is when a feature has both an addr:place and and addr:street tag, but there is already a good QA tool for this:

My idea was just to simply have a different colour pin (e.g. red) to be used whenever the there is an issue with the address tags. This would include any missing mandatory details (postcode, street/place, post town, housename/number) and also anything else that violates any tagging standard rules (e.g. addr:place and addr:street both present).
