*	Mapgen: Remove unused 'flat' and 'trees' flags from mg_flags	paramat	2016-08-04
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	When the 'flat' and 'trees' flags were moved into mgv6_spflags they were left in mg_flags in an attempt to support old mgv6 worlds. However their appearence in mg_flags causes confusion, also, later, old-world support was found to be broken for mgv6 worlds with 'notrees'. This commit cleans up the mess and comes a month after a thread warning of the change, and explaining the required action, was posted in the news subforum. Only old mgv6 worlds with 'flat' or 'notrees' are affected, a small minority of worlds, the required action being correctly setting these flags in mgv6_spflags. Disable a section of the 'map settings manager' unit test which is to be changed as it is causing problems for pull requests.
*	Add MapSettingsManager and new mapgen setting script API functions	kwolekr	2016-07-03
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This commit refactors the majority of the Mapgen settings system. - MapgenParams is now owned by MapSettingsManager, itself a part of ServerMap, instead of the EmergeManager. - New Script API functions added: core.get_mapgen_setting core.get_mapgen_setting_noiseparams, core.set_mapgen_setting, and core.set_mapgen_setting_noiseparams. - minetest.get/set_mapgen_params are deprecated by the above new functions. - It is now possible to view and modify any arbitrary mapgen setting from a mod, rather than the base MapgenParams structure. - MapgenSpecificParams has been removed.
*	Dungeons: Generalise use, add capabilities, various modifications	paramat	2016-06-17
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	- Generalise node names to c_wall and c_alt_wall - Remove 'mossratio' and instead disable alt_wall loop if c_alt_wall == CONTENT_IGNORE - Use one generalised 3D noise for alternative wall nodes and in mgv6 create moss distribution similar to the previous - Rename rarity noise to density noise and enable the option of multiple dungeons per chunk determined by the value. Recreate previous distribution - Add parameters for min and max rooms per dungeon - Add dungeon y limits - Integrate river water properly Generalisation is needed now that we have sandstone and desert stone dungeons by default and can choose any node for alternative structure. The current code is based around cobble dungeons with mossycobble alternative nodes, the 2 noises controlling the alternative nodes are based on wetness. Enabling multiple dungeons per chunk with definable number of rooms allows the option of very dense and complex underground structures that could interconnect to create megastructures. Y limits are added to be consistent with other mapgen elements, and enable locaton of dungeon or megastructure realms as part of our 'stacked realms' philosophy.

*	Lighting: Fix nearly all issues	kwolekr	2015-01-04
\| \| \| \| \| \| \| \| \| \| \|	The cause of a single light source seemingly being lit without spread was due to its creation in the +Y mapblock boundary layer during map generation, which was ignored as the overtop. This overtop explicitly needs to be omitted during sunlight propagation, however. To accomplish this, Mapgen::calcLighting() was split into separate functions taking separate parameters. Additionally, do not diminish light too early during spread. This fixes the output inconsistency between Map::updateLighting and Mapgen::calcLighting.
