Part 1:
- Use only one message entry for "Please register", that may have to be adapted to reflect the proper /register arguments
- Remove other message entries from code and from the messages files
Breaking change: reg_email_msg is also removed
- Split sole setting to two: one defining the registration type, and one defining what the register command should take as second argument
- Contains ugly code that will be fixed with a later issue
* the methods inside it renamed to fit with class name
* cache folder changed into playerdata
- Renamed LimboPlayer to PlayerData
- Added fly speed to PlayerData
- Removed player's name from PlayerData object
- Added getPlayerLocationOrSpawn method in spawn loader.
- Create class to handle the creation of "LimboPlayer tasks" (adds encapsulation, reduces duplication)
- Move group setting into its own class because (mutual dependency between LimboCache and PermissionsManager otherwise)
