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.

If size limit is exceeded, the luacontroller overheats. Overheating will cause the memory
to be erased.

This caused #238, reverting that commit fixes #238.

This reverts commit 30468b09.

Use right mouse button instead of left to press button and change state of switch and lever.

also shrunk the base part down by a very tiny amount to help avoid z-fighting with neighboring
water (scaled to 0.9995 percent)

corrected misaligned verticies, removed doubles, made better UV maps that use multiple
materials (allows to use multiple small textures)

Don't refer to LIGHT_MAX global; use default.

The LIGHT_MAX global is created in the legacy.lua file in the default
mod; it states that it's there for backwards compatibility, but it would
be better to reference the proper value inside the default table.

Register only locked nodes as stoppers

This was suggested here:
https://github.com/Jeija/minetest-mod-mesecons/pull/216

Remove insulated t-junction and crossover from craftable group

Thanks to HybridDog for spotting that

Register chests and bookshelves as stoppers

Adjust textures and inventory images to it

cause any bugs, but unneccessary sounds (experimental change)

state when the mesecons signal changes, no matter what state they're in

Use dye for lightstone recipes

* Enable glass and obsidian glass doors to be used with mesecons
* Doors can receive signals from a vertical wire placed two
  blocks beneath them, use this to create mesecon-controlled
  double doors
* Fix textures for both git upstream and stable minetest_game
* Shrink code size
* Rename mesecons_compatibility to mesecons_doors.

Fix doors texture names

Use group:sapling for power plant, blinky plant recipes
