Yey, I managed to fix a longstanding bug within my workspace

This may not change anything for the plugin, but my motivation to make landlord greater again.
Features:
+ PlaceholderAPI Integration:
ll_ownedlands - Your OwnedLand count
ll_claims - The amount of claims you have
ll_currentLandOwner - owner of the land you are standing on (for tablist)
ll_currentLandName - landname of the land you are standing on (for tablist)
+ Translation for Confirmation GUI
+ /ll update <World> - Updates all lands with the new farewell/greeting message
+ Support for LandLord-DynMap (I will upload a seperate Resource soon)
Bugfixes:
- Fixed a bug which let landlord operate without having ProtocolLib
- Proper Fix for the the alert system
- Fixed a nullpointer on /ll
- removed cost message when cost is 0
