What civ can see vs what is there about civ2-clone HOT 2 OPEN

To Tile class I've added visibility data of tiles, tile improvements and units for each civ. This is basically what each civ sees. Each of these properties is bool[8] (the data for index 0=barbs is not read, so it's always false).
The City class also now has two properties:

• WhoKnowsAboutIt shows which civs have knowledge of this city's existence
• LastSizeRevealedToCivs shows city size that each civ sees for this city

Also for .sav file two different parameter types are read - e.g. MapIrrigationVisible is what each civ sees and MapIrrigationPresent is what is actually there.

I've additionally read secondary maps data in the latest commit, which is necessary since TOT can have 4 maps and each unit/city/tile should have a mapIndex (which is always 0 for MGE and can be 0...3 for TOT).

I tried mapping those fields in the interface but I got nothing, will check with a better sav when I have access to windows next
