Bugs Fixed:
- fixed an issue with boosters not showing in /lps bp if the player didn't have any boosters
- fixed a tps issue with boosters

Changes/Additions:
- Added a new setting in EXP.yml to let server owners pick weather or not to take exp from players when they place ores.
- Recoded the way boosters countdowns work, it will no longer save the number to a yml but instead a hashmap to save on tps,
- recoded the way players levelup, (api for it will be coming soon)
