Subject: Adding Generator For Single Piece Structures (#4830)

* the beginning of a magnificent work - added basic files and classes without functionality

* fixed checkstyle

* added imports

* moved imports

* - Adding SinglePieceStructureGen
- Adding a cPrefabChestStructure to generate Chests with contents
- Added the options and calls to the ComposableGenerator

* moved Globals to .h file

* removed the chest thingy from the code (for now)

* Update SinglePieceStructureGen.cpp

* readded whitespace

* renamed to SinglePieceStructuresGen for consistency
added new classes to test

* fixed small things (mostly style and cleanup)
removed loottables

* added small changes suggested by madmaxoft

* small change to documentation

* added check for allowed biomes

* check only the biome of the origin position

* fixed error on IsBiomeAllowed

* added new cubesets

* updated structures for with sponging

* updated biome names

* updated metadata to prevent crashing
removed debug output

* updated structures with sponging

* added sponging to deserterWell to make it disappear in sand

* small change in meta

* rename DesertTemple -> DesertPyramid

* minor style changes
