*	Replace instances of std::map<std::string, std::string> with StringMap	kwolekr	2015-05-19
\| \| \| \| \| \|	Also, clean up surrounding code style Replace by-value parameter passing with const refs when possible Fix post-increment of iterators

*	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)
