First update, woohoo!!

Important notes
- If you have permissions set, you'll have to change personalphantoms to pp at the beginning of each of the permission nodes
- The no-phantoms list is no longer stored in plugin/PersonalPhantoms/data.yml. Instead, the plugin will use scoreboard tags to mark players for no phantoms. The plugin will automatically convert the old YML/file data to scoreboard tags when the player joins the server, so there's nothing you need to do!
- If you were using the plugin as a dependency in your own plugin (why?), the Main class was renamed to PersonalPhantoms

Changelog
- Now using scoreboard tags instead of a YML file (old data conversion is automatic)
- Reorganized/cleaned up messages for toggling phantoms
- Renamed personalphantoms to just pp in permissions to shorten them
- Renamed Main class to PersonalPhantoms
