Ultimate VeinMiner

• Most of the commands used in dialogs now don't require permission level, but commands that modify the data packs configuration still require level 2 permission.

Fixes:

• Fixed a case where vein-mined blocks do not reach the [Max Block] limit when animation is off.
• Fixed the removal of mining tool custom data.
• Slightly changed sneaking detection for [Safety Mode].
• Improved performance.
