Fix for broken nodes (e.g. sugar cane) not updating and leaving floating bits
Short-term fix for minetest.dig_node not always working (checking for group dig_immediate = 3)
[Michieal] 83bc60722d Begin: make bamboo dig-able by Pistons for Farm Creation.
[Michieal] 449cbdb330 Make Bamboo & Bamboo items not sticky for pistons.
[Michieal] a44566f863 hijack the ABM to check for orphaned bamboo nodes.
[Michieal] 5dff9e1994 Fixed the ABM situation so that now bamboo "breaks" when pushed by pistons.
Probably not the most elegant, but hey. It works.
[Michieal] 76507025d9 Cleaned up the global function to match the current ABM.
[Michieal] dfa849e19a Merge branch 'master' into Bamboo-Piston-Dig
[Michieal] a5bdc8a166 fix bamboo mosaic recipe.
[Michieal] 14383d6c6f update mod.conf to use optional depends mesecons_mvps
[Michieal] f81d530912 Update init.lua to register dropper callback.
This enables the feature of unsticky pistons. This allows
for some nodes to be unpullable, but otherwise pushable or diggable.
A certain selection of nodes that can never be moved.
And, stops certain entities from being pushed if they shouldn't move.
Along with this change; I've also updated the rules regarding
pushing, and pulling of nodes & objects to be more accurate to MC.
Now allowing for more complex redstone circuits to be built.
Highlights:
* Kelp should no longer be able to survive without water
(by decreasing its height)
* When kelp is destroyed, each segment now drop a single kelp similar to MC.
* Significantly refactor how kelp grows and dig. Possible optimizations might be
included.
