Close map options on map click on mobile

[kylebarron]

On mobile, it would be nice to close the options div whenever you click away from it. It seems like a simple way to do that is to add it to the map's onclick function (not onhover). And only apply on mobile...

Looks like a standard way to tell if browsing from a mobile device.

Then also can have map options expanded by default on desktop

I tried this in 7c93fec but after testing it on my iPhone, it appeared to not detect that my iPhone XR was a mobile device.
