Ok a bigger patch and also a request of a feature that should have been implemented right from the start.

Changelog:

Version 1.8.3.1:

• Added: markUnbreaking has now a "set" parameter which defaults to true and lets you decide if a Block is marked to unbreakable or remove the marking.
• Fixed: Removing Unbreaking state was bugged out. (It tried to remove the position instead of the id related to the position)
• Fixed: Settings for leftclick were inverted. Left did set right and opposite.
• Added: more userfriendly name checks for left & rightclick, so you can just use "left/right" or "leftclick/rightclick".
