MasterCooldowns v1.6.1

FIXED
▪ A bug accidently introduced in v1.6 making the /mcd add command not work properly

ADDED
▪ 4 new placeholders: %mcd_active_<space separated list>%, %mcd_inactive_<space separated list>%, %mcd_isactive_<cooldown>%, %mcd_isinactive_<cooldown>% (read more on the GitHub repo) and new config options for placeholders
▪ Option to disable messages for /mcd add (see config)
▪ Customizable save interval and an option to disable the message sent in console when cooldowns are saved (see config)
▪ A way to accumulate cooldowns: /mcd add [player||*] [id] [duration] <accumulate> - By passing true as value for 'accumulate', if the player has an active cooldown with the same id, the 'duration' will be added to the existing cooldown (remaining time + duration)
▪ Improved cooldown lookup

FIXED
▪ The time left placeholder using the wrong time unit when the value was less than 1 minute
▪ Warning on startup caused by an api-version not being specified in plugin.yml

FIXED
▪ The in-game message throwing an exception

ADDED
▪ Config file
▪ Reload command (/mcd reload)
▪ New in-game help command with JSON support
▪ Ability to add a cooldown to all online / offline players at once
▪ Ability to remove a cooldown or all cooldowns from all online / offline players at once (See the in-game help command for more)
▪ Duration formatting options

FIXED
▪ Messages typos
▪ Error when cooldowns were saved
▪ Plugin not working on 1.8
