Function to create a MM spawner
Right now, there is no way to create a spawner without the function tool. If you try to do it with commands only, at least, it doesn't work (the spawner appears, but when you leave and play the dungeon, the spawner isn't there. It would be nice to have an API function or just another way to create the functions than with the function tool, since having them only there puts a bit of a limit with what we can do, especially with other plugins.
