Map readability

[TheTomCZ]

Some ideas for map:

1) Add option to show/hide pollution - in highly polluted factory, i cannot see anything for the red fog.

2) Filters - buttons to show/hide resources/factories/belts etc. - when there is everything shown at once, it's sometimes hard to find anything. And with buttons, legend - it took me a while to figure out which color represents what.

That would be nice

Hit ALT again to toggle the overlay for fatories and boxes and the red fog is also gone
