NOTE: You should reset your config after updating or add:
If freeze-radius is 0 it will be disabled

Added a new permission:

• sf.exempt.distance - exempt from the reuiqrement to be within a distance of whoever you're freezing

Thanks to _Krono for the suggestion

Upcoming: I'm going to be re-coding SimpleFreeze again and making the plugin 1.8 and 1.9 compatible
No need to update to add this just see the config section on the plugin page for 1.8 sounds if you aren't using 1.9
