SignColors v1.1.1 for 1.12

If you found a bug or get an error, please don't rate 1 star, rather contact me with your error message or bug description, so I can help you!!!

• Many code changes "under the hood".
  
• Removed /sc colorsymbol, because it forced to save the config, which removes most of the config comments.
• Removed signcolors.colorsymbol (see above).
  From now on you'll have to set the colorsymbol in the config directly.
• Added Tab-Completion. Only completes commands you have permission for.
• The /sc help now only shows commands you have permission for.
• All sounds from this plugin can now be changed in the config.
• The config has now a better style (comments are above each setting).
• Changed metrics to bStats.
• Removed custom logger.
  
• Language improvements.
• Updater no longer throws an exception, if the update server cannot be reached.
• Cleaner logging messages.
• Some bug fixes.
