Version 15.4.0

Added:
- Unknown command message.


Fixed:
- %displayname% not getting users nicknames set by Essentials.


Changed:
- Improved incompatibility check for running regular Bukkit.
- Changed messages.yml format - Compare to the GitHub wiki for the latest. This was mostly done to make it easier to edit messages and so you can have multiple lines with JSON, or have a mix of regular and JSON messages.


NOTE:
- messages.yml has been updated! Please compare and update yours to the GitHub wiki. If you don't update the format, no messages will be sent! Also, read the comments at the top of the updated file, it has more instructions on how the new format works.
