[v3.5.6] Bufixes and some new features

Planned:

• Fix/Improve API
• Add plugin to maven

Planned v3.6:

• Multiple tablists

Planned v3.7:

• Add Actionbars

Updates:

• Sadly the unlimited prefix/suffix was removed again because of some bugs that occurred. With that the HEX colored names also no longer work.
  However, there is an option in the config to enable it again if it is working for you: "ranks.useUnlimitedLongRanks: true"
• Added warnings for deprecated placeholders
• PAPI placeholder TPS now also works if the placeholder tps is not used in PowerBoard
• Made some error checks if the scoreboard config is messed up
• You can now set a specific prefix for a rank in LP API
• Improved UpdateChecker for more performance (ASync) and fewer IP blocks
• Command '/pb help': You can now only see the commands for which you have the perm
• Removed old '/sb' command (This command has been replaced by '/powerboard' and '/pb')
• Added tab complete for commands '/pb', '/powerboard'
• Changed no permission message for commands
• You can now toggle the scoreboard and tablist with '/pb toggle scoreboard'.
  The following permission is needed: 'powerboard.toggle.scoreboard'.
  Note: This does not remeber the state. If the player rejoins, the scoreboard and tablist will be displayed again.
  Use a custom plugin to save the state using the PowerBoardAPI.
• Corrected typos
• The readme file in the scoreboards folder is no longer generated (replaced by a link in default scoreboard.yml)

Code improvements:

• Prepared tablist for the multiple tablists update
• Made some changes in the TPS class
• Improved Scoreboard Animations
• Removed unnecessary variables
• Put the LuckPerms API rank things in an extra class

Will be removed in v3.6 (deprecated):

• Double tablist config update migration

Will be removed in v3.7 (deprecated):

• Old placeholders support
• Rename update migration
• Multiple scoreboard update migration
• Old "ranks.luckperms" config instead of the new "ranks.luckperms-api"
