UUIDConvertTool (offline mode) 1.0.0

I created this plugin to fast convert players files from 1.7.5 to 1.7.9 UUID style on my offline mode server.

How to use:

1. Stop your server
2. Delete all plugins on your server (or just rename plugins to plugins2)
3. Put UUIDConvertTool.jar in plugins
4. Create directory playerdata in your main world directory
   
5. Start server, look on console
6. Stop server when last nickname converted.
7. Delete whitelist.txt, ops.txt banned-players.txt
8. Upload your plugins again (or just rename plugins2 to plugins)
   
9. Change spigot to 1.7.9
   
10. Start server & Have fun!

Plugin works on spigot 1.7.5
REMEMBER TO DO BACKUPS!
