RPGPlayerLeveling:
* Updated to a newer version ( https://www.spigotmc.org/resources/rpg-player-leveling.11096/)
* Made some changes in the way the variables get replaced
* Added secure checks for some variables to prevent null exceptions
* Fixed console spam errors
* Re-enabled full variable support

Developer Comment: It lasted a long time to re-built the hole variable system
to make it work perfectly without breaking a other feature for it.
Also you can use all RPGPlayerLeveling variables in all modules of the plugin!
