Beta 20220416-SNAPSHOT

Changelog:
 - Changed the way classes interact with the PlayerHandler by using a getter instead of the actual field.
 - Added #isTool(Material) to ItemBuilder to check if an item is, in fact, a type of tool.
 - Created the UnbreakableTool listener which will grant the unbreakable status to a tool if a user is lucky enough.
  NOTE: This is a beta feature, and while it may remain included the way it works will most likely change.
