Allow people to move google maps marker when editing their address

Hello guys,

I'm writing this here as don't have a license anymore, but tough you may be interested, got few complains from people that they can't set their real address with Easysocial address fields, because Google has some low cover on some Asian countries.

Instead they suggested that because google can't find exactly their address, allow them to move marker on the map in order to select their correct address on the map.

Regards
