[PATCH] New random map Caledonian Meadows

[FeXoR]

See it's history at ​https://wildfiregames.com/forum/index.php?/topic/17642-random-map-realistic-terrain-demo

This map is IMO now ready to be added. The code has sadly become quite complex and I want to optimize it. However, IMO it's worth to be added so players can enjoy and test the map as well as the general approach of these kinds of maps in the comming Alpha 21.

Fixed text for the map description: Fertile lands surrounded by harsh terrain.\nRemains of recent snowfalls still haunt the forests, and torrential rivers from the snowmelt barely died away.\nAiming at a realistic terrain, this map might not always be balanced.

I didn't take a look at this vast amount of RMS code, that I don't know very well overall...

Placement logic seems fine with regards to the output. Perhaps we more stone/wood. Mostly concerned that some areas seem a bit empty. Perhaps you can place some actors like a campfire.

Don't know if it's easily possible but perhaps some areas in the wood can have some space for buildings?

Fixes description as proposed by Itms

[FeXoR]

Uses an initial heightmap to soften the issue of "to much woods", "to much water" etc.

[FeXoR]

More resource spots also including raider camps. Decreased incline on smaller maps.

In the older versions add_caledonian_meadows2016_9_25.diff​ and add_caledonian_meadows2016_9_25.diff​ there's a colon missing in the .json. This is also fixed.

Use vectors for setTexture, refs #4992.

Simplify duplicate Caledonian Meadows and Wild Lake height-based texture painting by using for-of loops, texture setter and vectors, refs #4845, #4998.
Allow setTexture to write to impassable tiles as reported by FeXoR some time ago, refs #4245.
