Minetest Server Utilities updated to 1.9.2

Another update to my utilities - The backup tool now can send out messages to the IRC channel to let people know the backup will be starting soon, when it is starting, and when it is done... You can get it here: sourceforge.net/projects/minetest-utilities/ - let me know if you have questions or want to suggest some changes.. If you are a client of mine I can update your server for you.
