Expect 2.1.XX updates to slow down for a bit as I shift gears and focus on getting 2.2 complete.

• Added the setting 'Skills.General.LimitBreak.AllowPVE' to advanced.yml to allow Limit Break damage bonus to apply in PVE again, defaults to false
• Updated Limit Break locale strings
• Fixed a few more places where 'Archaeology' was misspelled in the locale
• Added the setting 'ExploitFix.PistonCheating' to experience.yml at the request of a user
• Added a missing 's' to Nether_Bricks (thanks Sikatsu) in experience.yml

NOTES:
The Skill Tooltips are a bit limited right now, in the future they will be more flexible. In order to reflect that Limit Break doesn't always work in PVE (now up to server settings) I added a crappy note to its hover window tip. I'll be fixing this in the future.

You shouldn't need to update you config entry for Nether_Bricks, I believe that file updates automatically (the old config system is a bit janky, some stuff updates, some other stuff doesn't.)

PistonCheating prevents blocks from being marked "natural" once they've been moved, we've never had an option for this before.
A discord user requested it, its a strange request but I added it anyways.
Of course, it defaults to "true" which prevents cheating with pistons.
