*	Push error handler afresh each time lua_pcall is used	Kahrl	2015-08-27
\| \| \| \| \|	Fixes "double fault" / "error in error handling" messages (issue #1423) and instead shows a complete backtrace.
*	Improve Script CPP API diagnostics	kwolekr	2015-08-05
\|
*	Fix object reference pushing functions when called from coroutines	ShadowNinja	2014-10-07
\|
*	Only push the Lua error handler once	ShadowNinja	2014-04-27
\|
*	Remove lua_State parameter from LuaError::LuaError	ShadowNinja	2014-03-15
\|
*	Revert "Make sure we get a stacktrace for as many lua errors as possible"	ShadowNinja	2014-03-15
\| \| \| \| \| \| \| \|	This reverts commit 362ef5f6ced862daa4733034810d0b07e2ad5d89. Stack tracebacks couldn't be generated in LuaError::LuaError anyway and this caused a second, empty traceback in most cases. In cases where there wasn't annother traceback the stack had already unwound and the traceback was empty.
*	Make sure we get a stacktrace for as many lua errors as possible	Sfan5	2014-03-15
\|
*	Log guilty node name when allow_metadata_inventory_move/put/take fails	Kahrl	2013-12-18
\|
*	Handle LuaErrors in Lua -> C++ calls on LuaJIT	ShadowNinja	2013-12-18
\|
*	Pass a errfunc to lua_pcall to get a traceback	ShadowNinja	2013-11-15
\|
*	Omnicleanup: header cleanup, add ModApiUtil shared between game and mainmenu	Kahrl	2013-08-14
\|
*	Move scriptapi to separate folder (by sapier)	sapier	2013-05-25
	On the lua side, notably minetest.env:<function>(<args>) should now be replaced by minetest.<function>(<args>). The old way is and will stay supported for a long time. Also: Update and clean up lua_api.txt (by celeron55) Move EnvRef to lua and remove add_rat and add_firefly (by kahrl) Add separate src/util/CMakeLists.txt, other minor fixes (by kahrl)
