\| \| \| \| \| \| \| \| \| \| \| \| \|	Schematics can already be placed with a param2 value, but not simple 1-node plant decorations of the simple type. This adds a `param2` field to the simple deco type that is checked to be between 0 and 255, and put to the placed node at mapgen. This can be used to put a degrotate value in, or e.g. a fill value for leveltype nodes, or a place_param2 value at mapgen placement, or vary the shape of meshoptions plantlike drawtype.

\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	* Move included json code to jsoncpp subdirectory This is needed to avoid having to specify the minetest src directory as a system include when fixing the json includes. * Fix json includes They used "", so that the compiler searches the project's directory first. The result was that when compiling with a system jsoncpp, the project's own version of json.h was still included, instead of the system version. The includes now use <>, so a system location, or one specified with '-Ilocation' is searched only. * Fix for jsoncpp deprecated function warning When compiling with a newer version of jsoncpp (and ENABLE_SYSTEM_JSONCPP=true), jsoncpp emits a warning about a deprecated function that minetest uses.

\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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.

*	Add minetest.check_password_entry callback	est31	2016-05-30
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Gives a convenient way to check a player's password. This entirely bypasses the SRP protocol, so should be used with great care. This function is not intended to be used in-game, but solely by external protocols, where no authentication of the minetest engine is provided, and also only for protocols, in which the user already gives the server the plaintext password. Examples for good use are the classical http form, or irc, an example for a bad use is a password change dialog inside formspec. Users should be aware that they lose the advantages of the SRP protocol if they enter their passwords for servers outside the normal entry box, like in in-game formspec menus, or through irc /msg s, This patch also fixes an auth.h mistake which has mixed up the order of params inside the decode_srp_verifier_and_salt function. Zeno-: Added errorstream message for invalid format when I committed
*	Particles: Add option to remove particles on collision	Auke Kok	2016-05-28
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Adds the particle option `collision_removal = bool` Some particles are hard to use right now since they either go through solid blocks (without collision detection), and with collision detection enabled they (e.g. raindrops) would just stop dead on the floor and sit there until they expire, or worse, scrape along a wall or ceiling. We can solve the problem by adding a boolean flag that tells the particle to be removed if it ever collides with something. This will make it easier to add rain that doesn't fall through your roof or stick on the top of it. Or clouds and smoke that don't go through trees. Particles that collide with this flag are marked expired unconditionally, causing them to be treated like normal expired particles and cleaned up normally. Documentation is adjusted accordingly. An added bonus of this patch is that particles can potentially collide many times with nodes, and this reduces the amount of collisions to 1 (max), which may end up reducing particle load on the client.
