Hotfix 4: save storage fix, mining rig cap

Hotfix 4 (v1.0.4)

• Mining rigs take far less save space, fixing the "save storage full" problem.

• Mining rigs are now capped because of that save problem. Existing rigs above the cap keep working.

• INSANITY LAYER leaderboard cap raised.

• Armor stat label was mistranslated as "arm" in TR / ZH / RU, fixed.
