Major change: Documentation is now included with mesecons, the website just extracts the documentation in a more readable format

This makes development of new features easier, as documentation can automatically be updated on the website without modifying the website's code!
Every mod that has nodes in the mesecons modpack has a "doc" folder that contains subfolders with recipe, description and preview of the block. The website will discover which documentation is available
by reading the documentation.json file.

Settings can now be retrieved by mesecon.setting(<name>, <default>) and can be modified without
editing the source code by adding the setting to minetest.conf
For instance, you can add mesecon.blinky_plant_interval = 0.5 to minetest.conf in order to
increase the blinking speed.
Rewrite the blinky plant with nodetimers.
Fixes #161

flexibility and because it was never inteded to be OOP in the first
place.

mesecon.receptor_on and mesecon.receptor_off are provided by wrappers
(mesecon:receptor_on/off) for compatibility, but will be removed. Mod
programmers that use mesecons: Please update!

Also, fix microcontroller polluting the global namespace and remove some
deprecated stuff.

using two ABMs allows the engine to desynchronize them, which makes the
duty cycle unpredictable.

here and there to facilitate this.

Digging and footstep sounds for everything that needs them! Plus, pushing buttons, punching switches, and flipping levers all make sounds.

fixed deprecated/invalid recipes in lightstones.

fixed copy&paste error in one of the delayer textures

fixed recipe for player detector to rely on microcontroller instead of old IC

visibly connect to neighboring wires.

Upload after major code reorganization - Version 0.6 DEV - Split mesecons mod into several modules - [BUGGY?]
