Added a new option in the configuration file (config.yml) called force-hard-difficulty, true by default. Can be changed to false to stop the plugin from forcing the difficulty to hard on all of your worlds.
All commands now show their syntax when /help is used for them.
Added the SpigotMC page for this plugin as the website URL in the plugin.yml file.
Changes
The plugin now logs the settings to the console when it gets enabled (useful for debugging and checking if your settings are correct).
Fixes
Fixed bug where the plugin would not force the difficulty to hard (now only if force-hard-difficulty is true in the config) or change the hearts to hardcore (if hardcore-hearts is true in the config) on any new world created while the server is running.
Fixed bug where starting-lives.min and starting-lives.max in the config could be set to values that are not numbers, which would cause problems.
