Statues Mod

This release only brings changes which have been merged years before, but were never released. These are:

• Fixed crash when opening Showcases (by @Vexatos)
• Italian localization (by @TheVikingWarrior)
• Korean localization (by a deleted account)
• Russian localization (by @Adaptivity)
• Simplified Chinese localization (by @Guro2)
• "Refactored a lot of code" (by @Vexatos)

There are no code changes made by me apart from changing the version String to 2.1.5.
