[Export] Show MapImages for each map

[w1lla]

Hi,

When exporting results only the data is shown but not for instance mapImages: https://tm.mania-exchange.com/maps/screenshot/normal/228636

Hm, this is a very cool idea! I'll have to brush up on my knowledge of the mania-exchange api but i think that map images are accessible from a relatively stable url as long as you know the map ID number which we do in some cases.
I think we could implement this as a toggle selection option on the export window
