This makes a number of changes: * Remove the dependency on marshal by using string.dump and loadstring. * Use lua_tolstring rather than having Lua functions pass string lengths to C++. * Move lua_api/l_async_events.* to cpp_api/s_async.*, where it belongs. * Make AsyncWorkerThread a child of ScriptApiBase, this removes some duplicate functionality. * Don't wait for async threads to shut down. (Is this safe? Might result in corruption if the thread is writing to a file.) * Pop more unused items from the stack * Code style fixes * Other misc changes
