Readded a bugfix from a pre-version of SmoothTimber and made it toggleable to prevent SmoothTimber being a bit slower sometimes.

Added more messages to the message.yml
Added a % symbol at the end of each variable

Fixed a bug which caused people who are lacking the permission "smoothtimber.toggle" to be able to use /sm toggle

Renamed some messages in the message.yml
Recolored messages from &a/&2 to &d/&5
