Initial ChunkStay code.
Fixed gcc compilation.
Fixed ChunkStay initialization.
Fixed lighting thread queueing.
Moved a forgotten comment back to its place.
Merge remote-tracking branch 'origin/master' into ChunkStay
Added air, farmland and tilleddirt to items.ini.

Air hasn't been present at all, the others are usual synonyms.
Added AllToLua.pkg to MSVC project files.

MSVC ignores the file when compiling and it makes it easier to open it up for editing.
cLuaState::cRef can be unbound and re-bound.

This will allow us to store Lua references as member variables in classes and initialize those later than in the constructor.
Initial Lua cChunkStay export.
Debuggers: Disabled testing plugin calls.
First working version of cLuaChunkStay.

It works, but has random failures, probably due to threading issues.
Debuggers: Added a cLuaChunkStay test code.
Maybe fixed boat placing
Merge pull request #659 from tonibm19/master

Maybe fixed boat placing
Fixed stupid mistax in conditional

boats can't be placed if the face is not block_face_none and not block_face_YM, not if it is only not one.
Merge branch 'master' into boatsFix

Conflicts:
	src/Items/ItemBoat.h
Added additional parenthasies
Added cPluginLua::cOperation.

This class should be used to lock-and-access the plugin's LuaState. cPluginLua::GetLuaState() is unsafe and by this commit obsolete.
Updated MagicCarpet and Core
